Data Science vs. Business Intelligence: Key Differences

Posted on by Imarticus Learning

It is impossible for the world to function without data. With time, data has become an inseparable part of life and every process related to data stands important. Business intelligence (BI) and data science are two processes focused on data but they are different in their approach to it. 

Generally, data science focuses on making predictions or forecasts about future trends. Whereas business intelligence makes efforts on analysing past events to evaluate what has generated positive results in the past and what has not proven to be in the organisation’s favour. Data science is much more technical when compared to business intelligence which is more of an abstract concept that involves few technicalities. 

Read on to do about data science and business intelligence and what are the distinctions between the two.

What is Data Science?

Data Science Course

Data science is a specific field of research that employs sophisticated tools, procedures, and vast volumes of data. It aids data scientists in finding, following, and extracting useful information from data patterns. Making important decisions in business and finance requires this kind of information.

The field of data science can be characterised as one that uses sophisticated analytics, statistics, and scientific principles to glean useful information and draw insightful conclusions from both structured and unstructured data. These in turn help in making corporate decisions, developing strategy, and other activities like financial planning.

What is Business Intelligence?

Business intelligence is the process of enhancing a company’s trends and decisions through the search, aggregation, and evaluation of the accumulated data stored by an organisation. Business intelligence is one of the most profound and innovative technical concepts of the 1990s.

Business intelligence makes it possible to make decisions involving data technology. Initially taking the form of organised consumer data, business intelligence eventually started to influence big organisations’ choices. Business intelligence presents consumer data in representational form such as graphs, charts, tables, etc.

Difference Between Data Science and Business Intelligence

Both data science and business intelligence help convert structured and unstructured data into readable information to enhance the decision-making process. The distinctions between data science and business intelligence can be enumerated as follows: 

 

Basis Data Science Business Intelligence
Data type Data science mostly deals with unstructured or semi-structured data which is in real time and distributed. Business intelligence deals with structured data which is sliced and divided into warehouses.
Complexity The degree of complexity is higher in data science. Business intelligence is simpler in nature and involves low complexity.
Role  Data science uses mathematical tools and statistics to identify and evaluate data patterns, analyse them and make predictions about future trends. Business intelligence focuses on organising datasets, taking out useful information and showcasing them in representative or visualised form such as dashboards, charts, graphs etc
Focus Data science mainly focuses on the future and makes forecasts regarding the same. Business intelligence focuses on past and present performance.
Usage Data science is used by companies to make close to accurate predictions about future situations in order to increase profit and mitigate risks. Business intelligence is used by companies to identify the cause of any failure or success in the past to make changes in the present, accordingly.
Skills required Data science is a more advanced field as it is a combination of subjects like mathematics, statistics, programming language and machine learning. Professionals in data science must possess the skill of data modelling. Business intelligence requires a lesser qualification as compared to data science. Business intelligence is more about reporting and presentation of data in a representative format that can be done through Excel sheets. 
Tools and software Data science professionals must possess insights into predictive algorithms and be equipped with knowledge of programming languages like R and Python. The knowledge tools required by business intelligence professionals are Tableau, Watson Analytics, QlikView etc. It focuses more on the concept of data visualisation and extraction.
Process The nature of data science processes is active and repetitive and there is a larger scope for experimentation. Business intelligence processes are static in nature with zero to little experimentation. 
Flexibility As data science is futuristic, it provides more flexibility to add or delete data sources as per requirement.  Business intelligence is less flexible as the data sources have to be calculated and planned beforehand. 
Method Data science methods are mostly scientific, analytical and technical. Business intelligence methods are always analytical.
Type of approach Data science takes a proactive approach.  Business intelligence relies upon the reactive approach.
Data size The technologies used in data science can hold large amounts of data, that is, terabyte size. Business intelligence technologies and tools are not equipped with the facility of holding large amounts of data. Hence, they are restricted to small datasets.
Business value The business value of data science is considered to be more when compared to business intelligence as it is focused on the future and makes predictions to make the organisation better. Comparatively, the business value of business intelligence is considered to be lower than data science As it is restricted to extracting data and representing them in the form of charts and graphs.
Expertise role An expert in data science is known as a data scientist. An expert in business intelligence is a business user. 
Consumption of information Data science information is consumed at multiple levels in an organisation which includes the executive level, managerial level, enterprise-level and so on. Business intelligence information is mainly consumed at the department level and the enterprise level in a company.

Conclusion

Although both data science and business intelligence have very different approaches towards data, both of them effectively work with them. Business intelligence is advantageous at the initial point of establishing an organisation whereas adding layers of data science in the later part can make it more functional and dynamic. Data science and business intelligence professionals are in high demand as no sector can work without data.

What is Node.js and Why is it So Essential for Full Stack Development?

Posted on by Imarticus Learning

Developing an application contains various parts, one of those parts is the backend. While creating a backend, developers always try to use related and unrelated databases. During the development of backend servers, developers use  Node.js as an open server and Javascript as a coding language. 

Node.js has emerged to be a valuable open-source platform as it contributes towards client satisfaction. Hence, many new and old tech companies have adopted the Node.js platform as it works efficiently with full-stack development. Therefore, an excellent full-stack development course includes knowledge of Node.js as well. 

Let’s dive into this article to comprehend more about Node.js and how it is essential for full-stack development.

What is Node.js?

Node.js is a very popular open-source platform that is used during the JAVA backend runtime. It was developed in 2009 by Ryan Dahl. It assists to run the client’s programmes or applications that do not involve the client’s network. 

Node.js is based on event-driven software known asynchronous therefore it is perfect for applications that are based on data-intensive and real-time. Any JAVA full-stack developer uses Node.js to develop software, web, and application. 

What are the various features of Node.js?

Node.js is one of the most valued open-source platforms which is preferred by most companies. Therefore it is essential to know about its various features:

  • Node.js nature is event-driven as well as asynchronous. Therefore, it never has to wait for receiving data from any API and can easily jump to the next API. This procedure makes all the APIs non-blocking or asynchronous in nature.

As the APIs do not wait for the data single from the other API, they have a different method of collecting signals from other APIS. 

  • Node.js follows a single-threaded architecture which makes it scalable. Alo being asynchronous or non-blocking in nature makes it more scalable. However, in the case of traditional servers limited threads are made therefore it is not as scalable as Nodes.js. 

Hence, it can be concluded that Node.js deals with more server requests than traditional servers.

  • Companies tend to opt for that software that can be easily scalable. Therefore, the demand and popularity of Node.js is increasing with time. Many demands or requests can be handled skillfully with the assistance of Node.js. Scalability allows this open server to balance every load properly. 

Another, feature of Node.js is that it can divide applications into several horizons which allows to customise the server accordingly for different clients and their preferences. 

  • Node.js had a rapid runtime or execution time. This is because it uses the V8 Javascript which is a fast runtime motor. This exact same runtime moto is used by Google Chrome hence it has a fast execution speed.
  • Node.js is one of the most compatible open sources as it can be easily used on any system like Windows, MacOS, UNIX, etc. 
  • Node.js is a very developer-friendly open server as it uses the JAVA script. JAVA is one of the most popular and easier computer coding languages. Hence, most of the developers know how to work with JAVA and it becomes easier for them to work with Node.js.
  • Node.js is a buffering free open-server. This means that data never buffers while working with Node.js
  • Many open servers take a long period to stream data. On the other hand, data are streamed rapidly while working with Node.js. Therefore, Node.js enhances the speed of uploading files as well as video streaming

Why is Node.js essential for full-stack development?

Node.js has emerged to be a boon for full-stack development. Here are a few essential points that will vividly explain the importance of Node.js for full-stack development:

Scalability

Node.js is essential for full-stack development because of its scalability. A developer can scale their programme in two ways by using Node.js. One is the horizontal orientation and the other one is the vertical orientation.

To scale horizontally a developer needs to add more nodes to the current programme. Developers can also add extra resources to the nodes by using the vertical orientation. 

Easily Comprehensive

Developers can easily comprehend and work with Node.js while working with full-stack development. Most of the front-end developers work with the JAVA scripture. Therefore, it is easier to work with Node.js while creating the backend of the programme. 

Caching is highly used to eliminate loading time

Node.js also eliminates workload by using caching. It is one of the most important features of Node.js which assists the developer to re-execute various codes. Moreover, the previous codes get saved in the cache making it easier for the developers to search those codes later on.

Economical

Working with Node.js is economical as it eliminated the load of working with two teams. Developers can programme server-side, backend, and frontend easily with the assistance of this open server. 

Easily Expandable

Node.js can be easily expandable to accommodate certain essential and enhanced requirements. Therefore, Node.js is important for full-stack development as it requires a lot of necessary additions.

Example of Node.js Usage in real life

Netflix is one of the most prominent companies that widely use Node.js. Previously, they were just using Javascript as well as JAVA. Then its startup time was around 40mins.

However, they were quick to discover the abilities of Node.js and adopted it. The startup time which was previously around 40 minutes was reduced to 40 sec with the assistance of Node.js. The scalability and data-incentive application of Node.js helped Netflix to grow.

A database collects data accessed, managed, and updated to meet the immediate need. As a Java full stack developer, storing data in a unified database is vital, which can help address them efficiently.

A database makes it easier for organisations to access and restrict access to specific files at a point. This data is then used in different organisations, including education centres and small to large-sized businesses.

Among the many databases that have made their way into the mainstream system, relational and non-relational databases rank at the top.

History of Relational and Non-Relational Databases

The history of these two popular databases dates back to 1970 when IBM’s lead computer scientist. Edgar F. decided to publish an academic paper hoping to remodel data in a new and more efficient way. He named it ‘A Relational Model of Data for Large Shared Banks.’

 Another attempt was made in 1998 with Carlo Strozzi when he decided to use the term ‘relational’ in NoSQL. 

Similarly, in 2009, Johan Oskassin and Eric Evans used the reversal term ‘non-relational’ database in the SQL server. Gradually, it became relevant and has been adopted as a database management model. 

A recent report published by Statista in 2022 establishes that Oracle ranks as the most popular in terms of relational DBMS (Database Management Systems). This is evident in its 1266.89 position as seen in the report.

As a Java full stack developer, it is vital to experiment with the different databases before moving to the one best for the task.

Relational Databases

A relational database refers to a database type that enables storing, organising, and managing data with the help of tables. 

Relational data is often structured with the help of tables assembled using rows and columns for better representation. It allows linking data from one table to another or multiple tables simultaneously.

A table can hold up to one data entry or object simultaneously. The columns help put a data store and store. The rows, on the other hand, link the record with data points. A schema also exists, defined as the relationship between a table and another table. 

This connection is called ‘relationships’, which is then put forth with the help of keys —both primary and foreign. 

Pros 

The advantages of using the relational database are as follows –

  • Object-oriented programming – As it is mechanised to assist in Object-oriented programming, accessing relational databases is extremely quick and easy.
  • Data storage – As tables deal with a large amount of data, relational databases are a perfect space for all sorts of structured, semi-structured, and unstructured data.
  • Schema requirement – While schemas can be implemented, it is also not necessary at the same time, making them highly scalable.
  • Simple structure – Due to its unilateral approach, relational databases perform efficiently at a reasonable pace.

Cons 

Let’s have a look at the restrictions of relational databases.

  • Data redundancy – Inconsistency occurs due to the same data stored in several tables in the database, which can serve as a pathbreaker.
  • Transaction processing – Transactions aren’t a strong suit for relational databases as they require complex SQL queries. When dealing with a considerable amount of data, the system can slow down.
  • Complexity – Relational databases can be challenging to design due to multiple relationships and entities.
  • Scalability – As the database is limited, adding hardware resources can be tricky. It can limit the performance of the system.

Non-relational databases 

Non-relational databases are distributed structures that redefine the traditionally used tabular data storage structures. These databases utilise newer formats such as documents, key-value pairs, wide-column stores, and graphs to offer more flexibility.

NoSQL databases or non-relational databases offer a range of benefits, including better scalability, non-complex structures, and faster performance. 

This database type is well-suited for building web and mobile applications and big data analytics. A Java full stack development course can be beneficial for understanding more about non-relational databases.

Pros 

Here are the advantages of working with a non-relational database.

  • Flexibility – Non-relational databases come with flexibility due to the absence of a predefined schema. 
  • Scalability – These databases are highly scalable and designed to store large amounts of data, making them the ideal space for e-commerce websites.
  • Cost-effective – This database doesn’t require an additional hardware or software set-up making it ideal for startups and small businesses to cut down on operating costs.
  • Higher efficiency – Due to the absence of schemas and queries, they are easier to maintain and perform faster and more efficiently than relational databases.

Cons

A Java full stack developer must understand each database’s limitations, and it is important to note these points.

  • Poor scalability – Non-relational databases are designed to be scaled easily, making it harder to maintain large amounts of data.
  • Limited data integrity – Relational databases have a higher up in data integrity. Non-relational databases’ features make it challenging to maintain data accuracy.
  • Query performance – Regarding queries, non-relational databases perform slowly, which can result in poor performance.
  • Complexity – Compared to relational databases, non-relational databases have more capacity making them complex data holders. 

Examples of Relational & Non-Relational Databases 

Relational Databases have been in the news for quite some time due to multiple uses. Several servers, including Microsoft SQL Server and PostgreSQL have taken to the relational database system. 

Simultaneously, non-relational databases are implemented in several areas involving column stores and document-oriented databases. A full stack development course can help you get a hands-on approach to the different kinds of databases.

The table below differentiates non-relational from relational databases.

Relational Database Non-Relational Databases
MySQL Couchbase
SQLite Amazon DynamoDB
MariaDB Oracle Berkeley DB
Microsoft Access MongoDB
Apache Derby Cassandra
IBM DB2 Amazon ElastiCache
H2 Database Entry Amazon SimpleDB
PostgreSQL Huawei Cloud GES
Azure SQL InterSystems Caché
CloudSQL AstraDB

Conclusion

Both relational and non-relational databases have their advantages and drawbacks. Relational databases suit complex data-based applications, whereas non-relational databases are designed for systems holding large amounts of unstructured data. 

A full stack developer certification can be achieved with a decent understanding of the benefits and disadvantages of both databases. It can also make it easier to access both databases while also absorbing the ins and outs of the system.

Full Stack Developer vs. Front End Developer vs. Back End Developer

Posted on by Imarticus Learning

The need for web developers has increased dramatically in the current digital era as companies rely on their online presence to succeed. The escalating demand, meanwhile, has led to a lack of clarity on the many kinds of developers and their functions in developing a website or application. You might have heard the phrases “Full Stack Developer,” “Front End Developer,” and “Back End Developer.” 

But what do they signify, and how do they differ? We’ll describe the roles and responsibilities of each sort of developer in this post to help you determine which one is ideal for you.

What is a Full Stack Developer?

An individual who can work on a web application’s front and back end is a full-stack developer. The front end of a web application refers to the elements, such as the layout, design, navigation, and functionality, that the user sees and interacts with. The portion of the online application that manages logic, data, and communication with external services, including the database, server, API, and security, is known as the back end.

Full-stack web developers are in high demand due to their versatility and depth of expertise. An average full-stack developer can expect to earn between $112,788 and $150,000 per year, depending on their experience and skill level. 

A full-stack developer can start from scratch and build a fully working web application using their extensive understanding of web development technologies. There are several career options in web development. Typical technologies that a full-stack developer should be familiar with include the following:

  • The front end uses HTML, CSS, and JavaScript.
  • Front end frameworks and libraries, including Angular, React, and Vue
  • Backend code is written with Node.js, PHP, Python, or Ruby
  • Backend frameworks and libraries, including Rails, Laravel, Express, and Django
  • Backend database systems like PostgreSQL, MongoDB, or MySQL
  • For deployment and hosting, platforms and tools like Git, AWS, or Heroku

The benefits of being a full-stack developer

  • More responsibility and complexity are placed on you. 
  • You must oversee numerous web development layers and ensure they interact safely and seamlessly.

What is a Front End Developer?

Front-end web developers handle the design and user interface of the website. As you know, HTML serves as a webpage’s structural foundation. Cascading Style Sheets (CSS) can be compared to the skeleton’s body or physique. 

In terms of websites, CSS allows front-end web developers to alter the form of the body, which is analogous to setting up specific parts in advance to give a website a distinct look.  In the US, a front-end developer can expect to make around $104,893 per year. 

What are the benefits of being a front-end developer?

  • The current method is centered on a website that prioritizes web developers. 
  • Front-end developers that can support the website for many industries and are knowledgeable about all the tools are in high demand.
  • Innovative and imaginative problems provide difficulties for front-end developers. They must be prepared with a solution and the necessary skills to design the website in a way that may satisfy the specifications.
  • Regarding website front-end tools, developers may learn about the latest ones.

What are the challenges of being a front-end developer?

  • You must address problems with responsiveness and browser compatibility. 
  • You must adapt to the shifting expectations and preferences of users. 
  • Collaboration with other developers and stakeholders is required. 

What is a Back End Developer?

Backend developers must often be familiar with PHP, Ruby, Python, and other programming languages. Additionally, they must be proficient in database technologies like MySQL, Oracle, and Microsoft SQL Server. 

The developer community extensively uses PHP. For instance, the SQL database saves the data supplied by a user during registration on a website. The server-side language retrieves the data from the database each time a user logs in, and HTML then shows it on your screen.

Are you curious about the compensation packages for backend web developers? They often earn more yearly money than front-end developers, up to and including $128,880.

There are numerous pros and cons of being a back end developer.

What are the benefits of being a back end developer?

  • You have more logic and problem-solving in your work. 
  • You can use your analytical skills and technical knowledge to create complex algorithms and systems.
  • A back-end developer also deals with some fascinating technologies, so that’s not all. Consider databases, servers, APIs, and many specialized programming languages. 
  • Back-end developers are in great demand. Therefore you can very much name your price when it comes to wage discussions.

The Final Words

Each position has its difficulties and benefits, whether you decide to become a Full Stack Developer, Front End Developer, or Back End Developer. The future of web development careers is expected to develop quickly, and new technologies and frameworks are continuously being developed. 

 Finally, it’s vital to note that the titles of Full Stack Programmer vs. Front End Programmer vs. Back End programmers are often used interchangeably, but it’s important to understand the specific responsibilities of each role to determine which path is right for you.
