Pandas series

A Pandas series is one of the many data structures. It is a one-dimensional array holding data of the following types – integer, string, float, Python objects etc. Collectively, axes labels are known as indexes.

Series may be created using inputs like an array, scalar value or constant. An empty series may also be created. A user needs to get accustomed to the Pandas program in Python to delve into the series.  

Creation of a Pandas series is done using the following constructors – data, index, type and copy. Data can be any list, dictionary or scalar value. The index should be unique. Dtype refers to series data types while copy is used for copying data.

Pandas series needs to be studied since it is the basics of a DataFrame. DataFrame is a two-dimensional labelled data structure. It consists of rows and columns like a spreadsheet. Python Pandas tutorial coaches a student with both theoretical and practical knowledge of the Pandas series.    

If predetermined indexes are available, they may be utilised to access Pandas series objects. Indexing or subset selection in Pandas is the identification of certain data from a Series object.

Interconversion of series into Data Frame and vice versa is possible. In specific functions, merging of Data Frame with series is also performed. The study of the Pandas series covers a lot of Pandas series attributes and Pandas series methods to perform a variety of functions. 

It is recommended that you always solve a large variety of Pandas practice questions. This will help you to understand the Pandas series and what is Pandas in Python. A solid Python Pandas tutorial will have a good number of exercises and solutions to clear the reader’s doubts. 

Operations

The most important function of data science is to prepare the data for model building, exploration and visualisation. Pandas is an exceptionally useful package in Python with several in-built functions capable of arithmetic, rational and logical operations. Those special symbols that carry out operations on values and variables are known as operators.

There are seven frequently used arithmetic operators and operands in Python Pandas. They are addition, subtraction, division, multiplication, modulus, exponential and floor division.

The rational operators and operands compare a value with another which is greater than, lesser than or equal to it.

The logical operators and operands are generally applied in conditional statements, like true or false. Here, a couple of situations should be satisfied to fulfil an equation. 

Python Pandas tutorial helps a student to be a master of these operators. Practical knowledge of operations will help a student to understand what is Pandas in Python. There are quite a few data operations for the data frame, as follows –

  1. Row and column 

Selection of any value can be done by selecting the name of the row and column. Thus the representation is one dimensional and may be considered as a series. 

  1. Filter data 

Data may be filtered by using some special data frame functions.

  1. Null value functions 

Null values (NaN), as the name suggests, do not contain data for the given item. In Python Pandas, users have the benefit of applying several unique functions for identifying, removing and/or replacing NaN in the data frame. 

  1. String operation 

The string function in Pandas helps to deal with missing or NaN values in a data frame.

  1. Count values 

This operation supports locating the frequency of items.

  1. Plot 

Pandas deploy the plot function to draw the graph of the given data. The reverse 

the function of tabulation can be also performed from a given graph.

Thus, the operation helps users to rationalise data in the first phase and convert the inputs into visual graphs, histograms, pie charts, etc. for easy understanding. All the above-mentioned topics are well covered in the Python Pandas tutorial.

Advanced Certification in Cybersecurity and Blockchain: Mastering Emerging Technologies

In the rapidly evolving digital landscape, cybersecurity and blockchain technology have emerged as pivotal elements, revolutionising various industries and reshaping the future of technology. As organisations worldwide grapple with the complexities of securing digital assets and ensuring data integrity, the demand for skilled professionals in these domains has skyrocketed. 

Understanding Blockchain Technology

What Is a Blockchain? 

A blockchain is a distributed ledger or database that is shared by all nodes in a computer network. Though they have applications outside of cryptocurrencies, they are most recognised for playing a critical part in cryptocurrency systems that preserve a safe and decentralised record of transactions. Any industry can employ blockchain technology to make data immutable, or incapable of being changed.

The one place where confidence is required is when a user or program submits data, as blocks cannot be changed. This feature lessens the requirement for reliable third parties, which are typically auditors or other people who incur expenses and make mistakes.

Blockchain applications have multiplied since the launch of Bitcoin in 2009 thanks to the development of smart contracts, Decentralised Finance (DeFi) apps, Non-Fungible Tokens (NFTs), and other cryptocurrencies.

Why Is Blockchain Important? 

Blockchain is important because it provides a secure, transparent, and tamper-proof way of recording transactions and data. It eliminates the need for intermediaries, reduces fraud, and enhances trust in digital systems. Blockchain’s applications extend beyond cryptocurrencies to sectors such as finance, healthcare, supply chain management, and more.

Key Elements of a Blockchain

To fully grasp the potential of blockchain technology, it is essential to understand its core components:

  • Decentralization: Unlike traditional centralized databases, a blockchain operates on a network of computers (nodes), where each node holds a copy of the entire blockchain. This decentralized nature ensures that no single entity has control over the entire network, enhancing security and trust.
  • Immutability: Once a transaction is recorded on a blockchain, it cannot be altered or deleted. This immutability is achieved through cryptographic hashing, which links each block to the previous one, creating a secure chain of data.
  • Consensus Mechanisms: Blockchain relies on consensus algorithms such as Proof of Work (PoW) or Proof of Stake (PoS) to validate and confirm transactions. These mechanisms ensure that all participants in the network agree on the validity of transactions, maintaining the integrity of the blockchain.
  • Smart Contracts: These are self-executing contracts with the terms of the agreement directly written into code. Smart contracts automatically enforce and execute the terms of an agreement when predefined conditions are met, eliminating the need for intermediaries and reducing the risk of fraud.

Cybersecurity Course

The Importance of Cybersecurity

As the digital world expands, so do the threats that target its vulnerabilities. Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These attacks are aimed at assessing, changing, or destroying sensitive information, extorting money from users, or interrupting normal business processes.

With the increasing sophistication of cyber threats, robust cybersecurity measures are essential to safeguard digital assets and maintain trust in digital systems. Cybersecurity encompasses various practices, including network security, information security, application security, and operational security. It also involves regular updates and patching, employee education, and incident response planning.

Top 50 SQL Interview Questions and Answers for 2024-25

This article will cover 50 SQL interview questions and answers that are asked in SQL developer interviews. This article is for freshers, intermediates and experienced professionals who want to ace their next SQL interview.

In this age of digitisation and data dependence, knowing SQL will give an edge in various career prospects. SQL or Structured Query Language, is a database language for accessing and decoding complicated data in databases.

Top SQL Interview Questions

SQL interviews are tough. Interviewers look for individuals who not only know the basics of SQL but also have practical knowledge about it. Here are the Top 10 SQL interview questions and answers.

  1. Define SQL and its main categories.

    This is one of the basic SQL interview questions asked by any employer. SQL stands for Structured Query Language, and it is used to manage and change databases. Its categories include Data Query Language (DQL), Data Manipulation Language (DML), Data Definition Language (DDL), Data Control Language (DCL), and Transaction Control Language (TCL).
  2. Define a JOIN and state its types.

    This is one of the most important SQL interview questions for developers. A JOIN function combines data from more than one table by using a common column to connect them. There are several forms of JOINs, including INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN. These JOIN variants determine how data from the relevant tables are combined and obtained.
  3. Differentiate between DELETE and TRUNCATE commands.

    This is one of the most important SQL interview questions for experienced professionals. Specialists employ the DELETE command to eliminate certain rows from a database based on a criterion, allowing them to carefully eliminate records. TRUNCATE, on the other hand, deletes all rows from a database table without any constraints. TRUNCATE is quicker and requires less computing power than DELETE, but it does not record specific row removals.
  4. Define a primary key and a foreign key in SQL.

    A primary key serves as a distinctive identification for each entry in a database, ensuring the accuracy of data and entity originality. In contrast, a foreign key is an assortment of columns that creates a link between tables by mentioning another table’s primary key.
  5. Define normalization in SQL.

    Normalization is a strategy for streamlining storing information in the form of a database, decreasing duplication, and improving data quality. This method comprises breaking down the tables into simpler, interconnected tables and connecting them.
  6. Define SQL dialects.

    SQL dialects refer to the numerous free and commercial versions of SQL. SQL syntax is extremely identical across all variants, with just minor differences in extra capability.
  7. State the main applications of SQL.

    The basic applications of SQL are:
  • Manage database tables by creating, deleting, and updating them, as well as accessing and modifying their data.
  • Extract and consolidate the pertinent data from a single or many tables.
  • Add or Delete certain columns or rows from a data set.
  1. State the different types of SQL subqueries.

    These are the various types of SQL subqueries:
  • Single-row- returns a maximum of one row
  • Multi-row- returns a minimum of two rows
  • Multi-column- returns a minimum of two columns
  • Correlated- a subquery connected to the data contained in the outer query.
  • Nested- a subquery within a subquery.
  1. Define constraint and state its use.

    A collection of criteria that specify the kind of data that may be entered into all the columns of a table. Constraints maintain the confidentiality of information in a database and prevent undesirable activities.
  2. Define a schema.

    A set of database structural pieces, including tables of information, procedures that are stored, indexes, operations, and triggers. It depicts the general database structure, describes the interconnections between various information items, and assigns various access privileges to them.
Top SQL Interview Questions

Basic Interview Questions and Answers

The smartest way to crack a SQL interview is to have clarity and knowledge of the basics. Additionally, it also increases the chances of cracking the interview. The following set of questions will cover some of the basic SQL interview questions and answers.

  1. Define a database.

    A database is a planned set of data that is saved and accessed securely from a distant or localized computer system. Databases may be large and complicated, and these databases are created utilizing predetermined architectural and modeling methodologies.
  2. Define DBMS.

    The acronym DBMS refers to a Database Management System. It is a type of program that is in charge of creating, retrieving, updating, and managing databases. It guarantees that the information that is stored is consistent, structured, and easily available by acting as a liaison between the relational database and its intended users or applications.
  3. What is a Cross-Join?

    A Cross-join may be described as a cartesian good of both tables involved in the join. The table following the join has the same amount of rows as the combined product of the two tables. If a WHERE clause is implemented in a cross-join, the search query will behave as an INNER JOIN.
  4. Define a Subquery and state its types.

    A subquery is a query contained within one more query, referred to as a stacked query or internal query. It is employed to limit or improve the data requested by the primary query, hence limiting or improving the original query’s result.

There are two types of Subquey- Correlated and Non-Correlated

  • A correlated subquery can never be regarded as a separate query, however, it may allude to a field in a table specified in the initial query’s FROM clause.
  • A non-correlated subquery might be regarded as a separate query, with its output inserted into the primary query.
  1. Define Data Integrity

    Data integrity is the guarantee of data correctness and uniformity throughout its life. It is an essential component of the creation, execution, and upkeep of any device that gathers, organizes, or extracts data. It also establishes integrity limitations, which impose company standards on information as it is input into a program or system.
  2. Explain Data Definition Language.

    DDL or Data Definition Language permits the execution of queries like CREATE, DROP, and ALTER.
  3. Define data manipulation language.

    The Data Manipulation Language, or DML, is a method for obtaining and altering database information.
  4. Does SQL support programming language features?

    SQL, albeit a language, does not facilitate coding since it is not a language for coding, but rather a command-line language.
  5. Define a Default constraint.

    The DEFAULT constraint fills an area with preset and set values. When no alternative value is specified, the chosen one is applied to all newly created records.
  6. Define an ALIAS command.

    Aliases are transitory names assigned to tables or columns for the intent of a specific SQL query. It is employed when the title of an area or database is changed from its initial designation, but only temporarily.

SQL Interview Questions and Answers for Freshers

It is preferable for aspiring data analysts, to opt for a data science course with placement. Choosing a data science course that has placement can help to set foot in the industry sooner. Here are some SQL interview questions and answers for those who are just starting to work.

  1. What are the different types of SQL statements?

    There are four types of SQL statements. They are- Data Manipulation Language (DML), Data Definition Language (DDL), Data Control Language (DCL) and Transaction Control Language (TCL).
  2. State the difference between CHAR and VARCHAR data types.

    This is one of the most common SQL interview questions for freshers. CHAR is a fixed-length character string type, whereas VARCHAR is a variable-length character data structure. CHAR always utilizes an identical quantity of storage capacity, but VARCHAR utilizes just the space required for the data itself.
  3. Differentiate between INNER JOIN AND OUTER JOIN.

    The difference between INNER JOIN and OUTER JOIN are as follows:
INNER JOIN OUTER JOIN
INNER JOIN retrieves the identical and appropriate data between both tables. OUTER JOIN retrieves every entry from the database fields.
An INNER JOIN returns entries that share similar fields or attributes. Since every record is sent back, the OUTER JOIN doesn’t need an identical column ID.
There exists no inner join variation. An outer join can be either left or right-side complete (cross join).
Inner joins are useful when several entry points for data are necessary. Outer joins are ideal if you do not require connected data entries as necessary.
The sluggish velocity that occurs in the inner join causes low efficiency. Outer joins perform superior to inner joins in SQL.
  1. Explain the ACID properties in SQL.

    ACID in SQL denotes Atomicity, Consistency, Isolation, and Durability.
  • Atomicity: Guarantees that an operation is handled as a single piece of activity that either finishes or does not.
  • Consistency: Guarantees that the relational database is in an identical state before and following the operation.
  • Isolation: Allows numerous actions to occur simultaneously without influencing one another.
  • Durability: Ensures that when an operation has been committed, the modifications are enduring, even if the system fails.
  1. Define a SQL index.

    A SQL index is an arrangement of data that speeds up retrieval of information activities on the database tables by allowing rapid utilization of rows depending on the contents of specific fields.
  2. What is an SQL trigger?

    A SQL trigger is a collection of SQL commands that run periodically as a reaction to specific events, including INSERT, UPDATE, or DELETE actions on a database table.
  3. Define a SQL transaction.

    A SQL transaction is a set of a few SQL statements performed as one piece of work. Transactions protect the integrity of data by enabling activities to be either entirely performed or completely reversed.
  4. What is a self-join in SQL?

    This is one of the most asked SQL interview questions. A self-join is a type of join procedure that joins a table to itself. It serves to merge rows from an identical table using an associated column.
  5. Differentiate between a view and a table in SQL.

    A table is an actual storage component that contains data, while a window is an electronic table created from several tables. Views cannot save data, but they do give a means to show data from tables.
  6. What is an SQL injection?

    This is one of the popular SQL interview questions for freshers. SQL injection is an approach for exploiting user data via website submissions by inserting SQL instructions as statements. Simply said, unscrupulous individuals can use these assertions to influence the program’s internet server.

SQL Interview Questions and Answers for Intermediates

These are some of the most asked SQL interview questions and answers to intermediates and developers. 

  1. Define a function in SQL. State its use.

    A database object that represents a collection of SQL commands frequently employed for a particular task. A function accepts certain parameters as inputs, calculates or manipulates them, and then delivers the output. Functions increase the understanding of code and prevent unnecessary repetition of programming snippets.
  2. State the different types of SQL functions.

    There are two types of SQL functions- Aggregate and Scalar Functions. Aggregate functions act on many, generally aggregated records from a table’s given columns and produce a single result. Scalar functions deal with specific values and ultimately produce a single output.
  3. State the different types of aggregate functions.

    AVG()- returns the average value
    SUM ()- returns the sums of values
    MIN ()- returns the minimum value
    MAX ()- returns the maximum value
    COUNT ()- returns the number of rows, including NULL values.
    FIRST ()- returns the first value from a column
    LAST ()- returns the last value from a column
  4. Define case manipulation functions.

    Case manipulation functions are a particular category of the character operations used to manipulate the formatting of textual information.
  5. State the difference between local and global variables.

    Local variables are only accessible within what function they were defined in. Instead, global variables are identified outside of any function and maintained in persistent memory frameworks, allowing them to be utilized throughout the whole program.
  6. State the difference between a primary key and a unique key.

    Although both forms of keys assure distinctive values in a table’s section, the first distinguishes each record, whilst the second prohibits redundancies in that category.
  7. State the difference between renaming a column and giving an alias to do it.

    Renaming a column completely alters its real identity in the initially created database. Assigning an alias to a column is to give it an interim title when running a query using SQL, to make the source code more understandable and concise.
  8. Can a view be used if the original table is deleted?

    No. Any views that utilize the table in question will turn obsolete once the main table is deleted. If we attempt to utilize a view like this, we will get an error notice.
  9. Can a view be created based on another view?

    Yes. This is additionally referred to as “nested views.” Nevertheless, we should steer clear of layering many views since it makes the code harder to comprehend and troubleshoot.
  10.  State the different types of SQL relationships.

    There are primarily three types of relationships:
  • One-to-one- Each record in a particular table matches exactly one record in a different table.
  • One-to-many- Each record in a particular table refers to multiple records in a different table.
  • Many-to-many- Each entry in the two tables relates to numerous records in the additional table.
Data Science Course

SQL Interview Questions and Answers for Experienced Professionals.

These are some important SQL interview questions for experienced professionals.

  1. State the different types of case manipulation functions available in SQL.

    There are three types of case manipulation functions available in SQL. They are:
  • LOWER- This method returns a phrase in lowercase. It accepts a string of characters as a parameter and produces it in lowercase.
  • UPPER- This method returns a string in uppercase. It accepts an address as input and comes back it in uppercase. 
  • INTCAP- This method returns a string with the initial letter in uppercase as well as the remainder of the characters in lowercase.
  1. Which function is used to remove spaces at the end of a string?

    The spaces are eliminated using a trim function.
  2. Which operator is used in queries for pattern matching?

    A Like operator is used to get specific data by looking for a specific pattern in the where clause.
  3. What is SQL Order by the statement?

    This statement is used to classify the recorded data in either ascending or descending order based on multiple columns.
  4. Are NULL values the same as zero or a blank space?

    In SQL, zero or blank spaces are distinguishable and contrasted with one another. One null could not be considered equivalent to a different null. Null indicates that data may not be given or that no data exists.
  5. Why is group functions required in SQL?

    Group functions or aggregate functions are used to group values of multiple rows as input on certain criteria to form one single value.
  6. Define Nested Triggers.

    A nested trigger incorporates its data alteration mechanism.
  7. State the operator that is incorporated for appending two strings.

    The “Concentration operator” is used to append two strings in SQL.
  8. Define a cursor.

    The pointer represents a Temporary Storage or Work Station. The database engine allocates it when the user performs DML actions on the table. Cursors are employed to save tables of data.
  9. Explain the ON DELETE CASCADE constraint.

    In MySQL, an ‘ON DELETE CASCADE’ constraint is employed to purge entries from the youngest table whenever the main table’s entries are eliminated.

But what is Python? Python is one of the simplest yet most useful programming languages. A survey showed that 49.28% of developers across the globe use Python, making it third on the list of most used programming languages.

It is a general-purpose language used for creating various applications, including web development, data science, automation, etc. Today, if you want to make a career in data science, understanding the nooks and crannies of Python is very important.

In this blog, we will learn about the key features of Python.

What is Python?

Python can be defined as a high-level, open-source, object-oriented, general-purpose programming language. Does that sound like a lot? Let’s break it down.

  • High level: Allows programmers to develop computer programs that are independent of the type of machine it is running on.
  • Open source: The language is free and available for further improvements. Programmers can add a helpful feature or fix a bug, there are no restrictions.
  • Object-oriented: An object is a data field having unique behavior and attributes. An object-oriented programming language is a model that organizes software design around objects.
  • General-purpose: The programming language can be used on any kind of platform. It is not specialized for any kind of problem.

It is widely used in software development, web applications, machine learning, and data science. Python has gained popularity because it is easy and efficient and can run on many platforms.

For entry-level coders, Python is one of the best programming languages to start with. Its versatility and easy-to-interpret tools have made Python a beginner-friendly programming language.

How did Python gain popularity?

Python features and advantages make it a popular coding language. Even people who do not know coding have heard about Python. It started as a hobby project and soon turned into the successful giant that it is today. According to a survey, the size of the Python community in the world is 44.6%, making it third on the list.

Here are some reasons why Python continues to gain popularity:

  • Easy to read: Python code uses English keywords. It has a simplified intuitive syntax that makes it easy to read. For people entering the world of programming, Python is easy to interpret. One can simply understand what the code is meant to do by looking at it.
  • Active community: Unlike the English language, Python programming language is fairly new. Every programmer is trying to learn how to work around the language. Python has built a dedicated user community in the last thirty years of its running. This community has developers of all skill levels. Programmers have easy access to guides, documentation, tutorials, and more. Developers from the community also crowdsource their work to find effective solutions.
  • Flexible and portable: Python is not domain-specific. Which means, it is not designed for certain applications only. Python can be used to develop nearly all kinds of applications in any field. Python is also portable. This means, unlike some languages which need to be modified to run on different platforms, Python doesn’t. It is a cross-platform language. The same code can be run on any operating system using a Python interpreter.
  • Broad standard library: The Python library is available for anyone to access. This means that programmers don’t need to write code for every function. Built-in modules are available to help with issues that might come up during coding.
How did Python gain popularity

Advantages of Python programming

Python is a flexible, powerful, and easy-to-use computer language. It has gained a lot of popularity and is widely used for many reasons. Here are some Python features and advantages:

  • Higher productivity: Python has a lot of uses. It is a simple language that allows programmers to focus on solving the issue. Rather than worrying about the syntax. For beginners, this is ideal cause they don’t need much time to learn about the syntax of the language. With Python, programmers can complete more assignments with less code.
  • Supports multiple programming models: Python supports procedural, object-oriented, and functional programming. The object-oriented approach facilitated code modularity, reusability, and extensibility. This is done using the four pillars of OOPs – inheritance, abstraction, encapsulation, and polymorphism. Using functional programming, programmers can write clearer and bug-resistant codes.
  • Test-driven development: With Python, one can easily do test-driven development (TDD). Programmers can easily write code and test it at the same time. Using the TDD approach, programmers can test cases before creating the source code.
  • Frameworks and libraries: Python has frameworks and libraries for practically every application domain. For example, NumPy, a Python toolkit is used for altering multidimensional arrays along with performing high-level mathematical operations. Ggplot, Matplotlib, Plotly, and Seaborn are some of the graphics and visualisation Python libraries. Programmers who want to do web programming can use popular Python frameworks such as Bottle, Django, or Flask. These are just a few examples, there are several more offering various features.
  • High-earning prospects: Software developers are needed in almost every industry. Python professionals are among some of the highest-paid developers. Companies are always on the lookout for well-trained Python professionals.

Characteristics of Python

Now that we have learned the advantages of the languages, what are the key features of Python? Python offers a lot of features which makes it a popular programming language. Here are a few key features of Python:

  • Interpreted language: Python by definition is an interpreted language. This means each line of code is executed separately by the Python interpreter. This makes the debugging process much easier. Furthermore, when Python code is executed, it is immediately translated to byte code. This makes execution simpler and runtime is saved in the long run.
  • Cross-platform language: Python is a cross-platform language. This is one of the key features of Python. It can run on different operating systems such as Linux, Windows, and macOS without any alterations. This helps developers to write their code once and deploy it on various platforms. It is a great way of saving time and effort in application development. Cross-platform compatibility makes Python ideal for modern software development. With this, applications can reach a broader audience across various devices and operating systems.
  • Dynamic language: Python is a dynamically typed language. This means the type of variable is determined during the runtime. In the case of statistically typed languages such as Java or C++, explicit type declarations are needed. However, Python does not need that. Python also allows variables to be bound to different objects at runtime. This helps in creating reusable codes and reduces code redundancy.
  • Object-oriented and procedure-oriented: An object-oriented programming language focuses the code design around objects and data. Not on logic and function. On the other hand, a procedure-oriented language focuses more on functions. One of the key features of Python is that it supports both object-oriented and procedure-oriented programming.
  • Read-Evaluate-Print Loop (REPL) Environment: Python offers are REPL environment or an interactive shell. It enables developers to experiment with code snippets easily. It also allows developers to execute their code and immediately see the output. This facilitates rapid experimentation and prototyping. REPL is one of the key features of Python plays a crucial role in development and debugging. In this way, developers can test code snippets, check results, and refine the code.

Importance of Python programming in different areas

What Are the Different Types of Databases?

What Are the Different Types of Databases?

Understanding data and its storage is integral to anyone looking to kick start their career in data science. Today, even non-technical roles demand an understanding of data handling and management.

Data is any information that is stored in a system. Now if you are working with a small dataset, you can handle it manually. However, owing to the rapid digitisation of businesses, the influx of data has grown manifold. This brings in the need for different types of databases.

However, if you are someone who nurtures an interest in all things data, it is never too late. Consider enrolling in a data science course today to give your resume the edge it deserves!

What are Databases

Owing to all the hubbub about data management today, you must have come across the word “database”. A database is a structured collection of data that is stored on a system of your choice.

Typically, you would think of a database as a computer system, but your phone is also a database and so is your smartwatch. Any platform or device that stores information for you is a database. Broadly classifying, there are two different types of databases– internal and external.

Internal databases are the ones that companies themselves own such as data lakes and warehouses. External databases, on the other hand, are owned by third-party organisations and can be accessed on the Internet such as cloud-based storage solutions.

What is a Database Management System (DBMS)?

Now that you know what are databases, the next step after you have stored your data is to manipulate it, right? As in, you might want to perform some function on a selected section of the data, or even delete a part of it. This is where a different type of DBMS comes in handy.

A DBMS is a software system that is used to manage a database. It allows the user to store, retrieve or manipulate the data to make it more consumable and accessible. DBMS serves as an interface between the database and the user, without hampering data integrity.

Here, there is a provision for a database administrator (DBA) as well. The DBA is responsible for maintaining databases and ensuring their integrity, security, performance and availability.

Database Components

Different components work together to facilitate the creation, management and utilisation of different types of databases. Each component plays a crucial role in the overall functionality and performance of a database system.

  • Hardware
    The hardware aspect of a database is undoubtedly one of the integral components ensuring the smooth functioning of the system. It includes devices such as servers, networking equipment and storage devices that work together to optimise database scalability and accessibility.
  • Software
    Now that we have the hardware in place, we need to integrate database software into the system. Database software includes the database management system (DBMS), which is used to manipulate and interact with databases. DBMS provides functionalities such as data storage, retrieval, manipulation, deletion and security. To make it simpler, think of a DBMS as a librarian and the different types of databases as their library.
  • Data Procedures
    Data procedures refer to the methods and protocols used to manage and manipulate data within a database. Data procedures ensure that data remains accurate, consistent and consumable to authorised users. This includes defining data structures, implementing data integrity rules and establishing backup and recovery procedures.
  • Database Access Language
    Database access languages interact with databases and perform operations such as querying, updating and deleting data. SQL (Structured Query Language) is the most widely used database access language, allowing users to write queries to retrieve and manipulate data.
Data Science Course

About Primary Database Types

Depending on the user’s requirements there are different types of databases. They are classified based on the storage pattern, technique and accessibility. Broadly classifying the different types of databases, we have:

Centralised database

This is one of the different types of databases where all data is stored in a centrally monitored unit. The data can be accessed from any device after a user passes verification measures.

In this arrangement vendor intervention is significantly less as the datasets are all centrally stored. Hence, it is cost-effective and provides for better data consistency. However, centrally storing the data does have some demerits to it.

Owing to the large size of the repository, the buffer time is high and retrieval takes time. On top of that, the database may be relatively inexpensive to install but requires extensive maintenance.

Distributed database

Think of the distributed database as the polar opposite mechanism to the centralised database system. Distributed databases divide and compartmentalise datasets into different systems. This is done so that users can access only relevant information from their respective databases.

Two different types of databases constitute distributed databases– homogenous and heterogenous. The difference is simple. Homogeneous databases use the same devices and operating systems across units. For heterogeneous databases, the operating systems, application processes and hardware devices are all different.

Distributed database systems facilitate better scalability and growth across the organisation. It is also beneficial in a server-error scenario. As in, one anomaly does not disrupt the entire database and hinder smooth functioning. However, they are costlier to build and maintain due to the compartmentalised infrastructure mechanism.

NoSQL database

Structured query language (SQL) servers store extensive amounts of structured data. Now, NoSQL is the exact opposite of that. These databases store a wide variety and range of datasets. Also known as non-SQL database, this system stores data outside traditional storage norms of a tabular format as in relational databases.

This data storage system is also cost effective when compared to the traditional RDBMS. Maintaining a NoSQL database does not require powerful and extensive infrastructure. This allows companies to allocate resources effectively and provides for high scalability.

NoSQL database can be further divided into the following types:–

  • Key value storage
    This type of NoSQL database stores every data input with a key value or identification mark. It is the most commonly used method.
  • Graph database
    When working with an exponentially growing amount of data, graph databases come in handy. Social media networks use graph databases to store all the information they handle in graph formats.
  • Document oriented database
    Suppose you want to store your data in documents that are grouped as per the application code. This is where document oriented databases should be your pick. They group the data in JSON-like documents, in open interchange format that are both human and machine readable.
  • Wide-column store or column store database
    It is similar to storing data in relational databases. Data is stored in columns instead of rows to make it more consumable.

Cloud database

Imagine an organisation that has a huge volume of data to be managed. So, it might not want to get into the hassle of owning and maintaining an extensive database system. This is where cloud databases come in. These are data storage solutions that run in public or hybrid cloud environments.

Other than being cost-effective, cloud databases are also relatively more accessible than traditional databases. Owing to the huge influx of disparate data the need to scale and compartmentalise databases is essential to growing businesses.

Furthermore, cloud databases are customisable to the user’s needs. They are equipped with robust security measures and in-built data recovery mechanisms in addition to their high accessibility.

Relational database

You must have heard about storing data in rows and columns. Well, that is the principle of relational databases. Invented in 1970 by E.F. Codd, a relational database stores the data in tuples and attributes. It uses structured query language (SQL) to create a unique identification for each data that is entered into the system.

The relational database has four components which are popularly known as the ACID properties. They are:

  • Atomicity
    Like atoms are the smallest independent units of matter, operation is the smallest unit of a relational database. This means that an operation or transaction has to be completed in its entirety. In case that is not possible, the operation is aborted. This is in accordance with the “all or nothing” policy of an SQL server.
  • Consistency
    This property of a relational database ensures that the value of a data remains consistent before and after a function is performed on it. If the data is manipulated during an operation, the database should reflect the changes correctly.
  • Isolation
    This property ensures that simultaneous operations do not affect each other. Operations must not be visible to one another until they are completed and the changes are reflected in the database. This ensures that multiple users can access the same database independently without interfering with one another.
  • Durability
    Once an operation is completed, the changes it brings about are stored permanently in a nonvolatile memory. This means that even if a system failure occurs, the memory of the transaction will remain intact. The system will not revert to its previous state and the effect of the operation updates the database.

Object-oriented database

Also known as OODB, an object-oriented database functions on the basic definition of object-oriented programming (OOP). It stores data in the form of objects and classes. The object-oriented data model has three major components– object structure, object classes and object identity.

Object-oriented databases are used when you’re working with weaving complex data structures and techniques. It integrates all the core principles of OOPS such as polymorphism, inheritance and encapsulation. This significantly reduces the amount of translation required and thus makes retrieval efficient.

However, OODB structures are costly to implement, maintain and integrate in the system. On the other hand, OODB eliminates the concept of mapping, directly giving developers access to the database objects. In addition to supporting challenging data types, it also provides for efficient scalability of the database.

Hierarchical database

The hierarchical database structure is based on the parent-child model. Developed in the 1950s by IBM, it operates in a tree-like structure. This model views data as a collection of segments that form hierarchical relationships.

Segments can be connected in a chain-like structure through logical, directional associations. In this model, segments pointed to by logical associations are called child segments, while the segment pointing to them is the parent segment.

Hierarchical models are widely used due to their semantic and physical alignment with real-world biological, political and social structures. Also, they are suitable as physical models because of the hierarchical organisation of disk storage systems, like tracks and cylinders.

Network database

Although based on the principle of traditional hierarchical databases, network databases allow records with multiple parents. Although easy to design and maintain, network databases do not embody the tree structure.

Instead, they follow a graphical pattern defined by a schema containing the intra-data node relationships. Although network databases are preferred over hierarchical databases for more data independence, they still lack a flexible structure.

While creating the database there is a lot of flexibility, however, once populated, the structure is very rigid.

Conclusion

Different types of databases allow for greater accessibility of options for users with varied requirements. Depending on the resources at hand, users can opt for the database that best suits their needs.

However, maintaining these databases needs efficient experts who supervise the entire operation. If you are someone who is fascinated by data science this is your chance. The global demand for data scientists is projected to increase by 200% by 2026. So why wait?
