It came out for the first time in 1996 and is now one of the world’s most popular relational database systems. PostgreSQL is a popular choice for handling data for several reasons. In this article, we’ll examine five of the most convincing ones.

Reasons Behind the Popularity of PostgreSQL as a Powerful Data Management System

PostgreSQL is a powerful database management system, and it’s important to know why. It can help businesses make better choices about handling their data management needs. By learning about its perks, businesses can decide if PostgreSQL is the right database system for their requirements. PostgreSQL has something for everyone, whether you are a worker, a data scientist, or a business owner. So, let’s look at the top five reasons why PostgreSQL is a powerful database management system.

1. Free and Open Source

One of the major advantages of PostgreSQL is that it’s free and open-source software. This means you can use it without paying any fees. You also get the freedom to customize it however you want to meet your specific needs.  Since it’s open source,  you have access to the underlying code. This allows you to modify it, fix bugs, and contribute improvements back to the overall project.

The open-source nature fosters a large, active community of both PostgreSQL developers and users. Folks in the neighborhood provide helpful support and feedback.  Tons of online resources make learning and using PostgreSQL much easier. You can also join forums and discussion groups to ask questions and share your experiences with other PostgreSQL fans.

You can also use PostgreSQL with different frameworks and tools, such as Django, Laravel, Rails, Spring Boot, Hibernate, etc.

PostgreSQL also supports different data types and formats, such as text, numeric, date/time, geometric, array, JSON, XML, and so on1. You can also create custom data types and functions to suit your needs. PostgreSQL also supports non-relational statements like JSON and can be linked with databases like SQL & NoSQL.

3. Scalable and Performant

Another major benefit of PostgreSQL is its ability to scale to handle large amounts of data and transactions while maintaining fast performance. PostgreSQL can efficiently manage extensive databases. It supports tables of up to 32 terabytes and databases of up to 64 terabytes3. This makes it suitable for even the largest data sets.

PostgreSQL utilizes parallel query processing and data partitioning to improve the efficiency and speed of queries on large amounts of information1. This allows it to keep response times fast even as your data and usage grows. High availability and durability are also strengths.

PostgreSQL supports asynchronous replication and point-in-time recovery. Asynchronous replication allows you to maintain database copies on standby servers for redundancy, backups, or load balancing.  Point-in-time recovery gives you the flexibility to restore the database to any previous state in case of failure or data corruption. This ensures data is preserved and accessible around the clock.

4. Secure and Reliable

This data management system is secure and reliable. PostgreSQL can keep your data from being changed or accessed by people who shouldn’t be able to. PostgreSQL lets you use different encryption methods and techniques to protect your data while it’s in motion and sitting still. PostgreSQL also has several security methods and tools that can be used to check a user’s identity and give them the right powers.

PostgreSQL also supports transactions with ACID features. ACID is an acronym for atomicity, consistency, isolation, and longevity. These qualities ensure that your deals are carried out fully, properly, on their own, and for good. PostgreSQL also has data security features like a main key, foreign key, unique constraint, check constraint, and so on1. These features make sure that your info is correct and reliable.

5. Extensible and Customizable

Lastly, You can extend its functionality and tailor its behavior. PostgreSQL supports a variety of extensions and modules that add new features and capabilities. For example, there are extensions for:

Geospatial data – PostGIS allows you to store and query location data

Cryptographic functions – pgcrypto adds encryption and hash functions

Hierarchical data – ltree stores and queries tree-structured information

Key-value pairs – hstore stores key-value pairs within a single field

PostgreSQL also supports procedural languages that allow you to create functions and procedures using languages like:

PL/pgSQL (the default PostgreSQL procedural language)

PL/Python for writing Python code

PL/Perl for Perl

PL/R for R

PL/Java for Java

You can even create your procedural languages using the PL handler interface.

Node.js is a JavaScript runtime environment mostly used for the backend development of online projects. It enables the developer to produce dependable and effective server-side and networking web applications. 

Additionally, it is compatible with Windows, Linux, and OS X.

How Does Node.js Work?

Node.js processes client requests and generates responses using a single thread. It employs threads to handle I/O operations and demands, allowing for parallel execution and serving multiple clients simultaneously. 

Node.js manages concurrent requests without blocking the thread for any single request with its event loop-based architecture.

In general, Node.js works on two concepts – Non-blocking I/O and Asynchronous.

1. Non-blocking I/O

Node.js uses non-blocking I/O, enabling it to efficiently handle input and output operations without blocking other tasks.

2. Asynchronous

Node.js operates asynchronously, allowing code execution to continue without waiting for results, enhancing performance and responsiveness.

The Pros and Cons of Node.js

Pros

Powerful Package Manager and Support

Node.js uses npm as its primary package manager, offering access to an extensive collection of over 800,000 libraries and reusable templates. 

This vibrant ecosystem sees nearly 10,000 new libraries added weekly, continuously improving the technology. 

In 2015, the Node.js Foundation was established with the backing of industry giants such as PayPal, Microsoft, SAP, and IBM.

High Scalability

Node.js excels in scalability by handling multiple connections and prioritising requests, even with slower response times. This capability enhances performance and accelerates software development. 

With its event-driven and non-blocking nature, Node.js allows for the seamless addition of numerous nodes to the main programming function.

The scalability empowers developers to scale solutions vertically and horizontally, enabling businesses to extend software functionality, incorporate additional resources, and explore new capability paths.

Additionally, Node.js features a robust caching module, enhancing solution efficiency by caching data. These scalability features make Node.js an excellent choice for conventional software projects.

Vibrant Open-Source Community

Node.js benefits from an active and passionate open-source community that continuously contributes to improving the technology. 

The community fosters collaboration with thousands of developers worldwide, offers support, and shares reusable JavaScript code. This collective effort streamlines development and reduces time-to-market. 

Furthermore, the support of leading organisations adds to the strength of the Node.js ecosystem.

Simplicity and Lightweight Runtime

Node.js is renowned for its simplicity and lightweight runtime environment. The latest version, Node.js 20.2.0 with 9.6.6 npm, takes a mere 25.2 MB of space on Windows. The minimal footprint allows software experts to achieve similar functionality with less effort. 

Moreover, Node.js appeals to developers seeking a unified language for front and backend development. 

Its compatibility with JavaScript makes it accessible to developers proficient in the language. Engaging in Node.js discussions on platforms like GitHub provides quick access to valuable insights and assistance. 

Partnering with experienced Node.js professionals ensures the seamless functioning of both the client-side and server-side of web applications.

Node.js remains viable and outperforms its competitors in handling dynamic content. Node.js showcases effective resource utilisation, making it an optimal choice for modern, high-performing solutions.

Cons

Avoiding Nested Callbacks

When working with Node.js, developers must be cautious to prevent the occurrence of nested callbacks, also known as “callback hell.” 

Callbacks are functions that execute when Node.js completes tasks in its queue. Excessive use of callbacks can lead to deeply nested code structures that are challenging to comprehend and maintain.

The root cause of callback hell is often unclean code or lack of experience. It is advisable to engage a Node.js development partner who adheres to clean coding practices and possesses the expertise to simplify or refactor complex code to decrease callback hell issues.

Handling CPU-Intensive Requests

Node.js may not perform when faced with CPU-intensive computation tasks. While Node.js excels at prioritising incoming requests, this efficiency only extends to CPU-bound tasks and requests.

When Node.js encounters a CPU-intensive computation, it assigns it the highest priority. However, the heavy nature of such tasks can slow down the runtime environment. 

Consequently, Node.js is not the most suitable choice for solutions that require intensive computations.

Fortunately, in 2018, introducing the “worker threads” module offered a solution. This module enables multithreading in Node.js, allowing the runtime environment to handle CPU-intensive tasks. 

Developers can leverage this module to execute code in parallel across multiple threads.

Ecosystem Contribution Challenges

The JavaScript ecosystem boasts an abundance of packages, but the quality may only sometimes meet expectations. The vast array of options makes it tough for developers to select the best package, and not all packages can maintain high standards.  

But, it is essential to note that the core Node.js framework is meticulously maintained by its creators. The concern lies with the additional tools and components, where quality may vary. 

Choosing a reliable Node.js development company with extensive experience and a deep understanding of Node.js best practices is crucial to overcome this drawback.

Data is of utmost importance in the age of innovation and technology. We often enter the wrong type of data in a particular space, leading to many future mistakes. So, when entering data, we must ensure it is of the correct type or form. We can use HTML5 for data validation. Several web applications use HTML5 for validating data on the client end. 

HTML5 is the latest version of the HTML standard. It came into force in 2006. Notably, HTML5 data validation is a procedure that allows the browser to execute client-side validation without using JavaScript. HTML5 data validation is not as customisable as the JavaScript-based validations. HTML5 is one of the best tools for web development. 

In this article, we will discuss the scope of HTML5 data validation in detail.

What is data validation? 

Data validation is a procedure to ensure that a given set of data is accurate. It also verifies the quality of the data before using it. While moving or processing data, it is common to get corrupted. Data validation is crucial as it prevents data loss and helps to achieve accurate and consistent data.

What are the different types of data validation? 

There are several types of data validation. These checks ensure that data is correct. Here are a few of the data validation checks: 

• Checking data type

This type of check ensures that the “type” of the entered data is correct.

• Checking data range

This check ensures that the entered data falls into the predefined range.

• Checking code

This check ensures that the entered data follows a particular rule of formatting.

• Checking consistency

A consistency check confirms that the entered data is logically consistent.

• Checking format

A format check ensures that the entered data has the correct format.

What are the advantages of using HTML5 for data validation for web applications? 

User-friendly is the term we should keep in mind while designing or developing a webpage or web application. Web applications are stored on remote servers and delivered through various browsers. Although some web applications run on specific browsers, most can run on any browser. Using HTML5 for data validation ensures that the application becomes easy to navigate. Here are a few advantages that HTML5 data validation offers:

• Clarity

HTML5 is easier to understand and comes with some free functionality that makes the development procedure easier.

• For devices of various screen sizes

The files of HTML5 form validation are usually lighter than the non-semantic spaghetti code. It makes them more responsive in a variety of screen sizes.

• SEO friendly

The search engines using HTML5 emphasise keywords in headings and links, making them more SEO-friendly.

• Reduced load

Using HTML5 reduces the load on the network and the server.

How does HTML 5 data validation work? 

We can use HTML5 for various kinds of web applications which require several inputs. Forms are an excellent example. An HTML5 application consists of HTML, Cascading Style Sheets (CSS) and JavaScript files. Below we will elaborate on how HTML5 works:

Setting up data validation with HTML5

Here we will discuss how HTML5 validation works to simplify web application development. Various functions help in data validation. Some of these are:

• Required

The input “required” can be used to make fields mandatory. For example, while filling in any job application form, the field “first name” is marked as “required”.

• Type

The input “type” can be used to restrict the type of data required. 

• Length of data

We can use some inputs to restrict the length of the data. For example, we can use the inputs “minlength” and “maxlength” for text data. Similarly, we can use the inputs “min” and “max” for number values.

• Pattern of data

We can use the input “pattern” to specify the data pattern needed to match the entered data. For example, while entering “email”, there is a specific pattern that we need to follow.

Now, we need to assign two pseudo classes. These are:

• If the values entered in the fields above match HTML5 validation, then we can assign it to the pseudo class “valid”. After this, if the user wants to send the data, the browser will submit it.
• If the values do not match, then we can assign it to the pseudo class “invalid”. In this case, when the user tries to send data, the browser will block it and show an error message.

Conclusion

If you are interested in HTML5 for data validation, then consider a career as a full-stack web developer. You can land lucrative job offers as full-stack web development is in demand.

Over the past two decades, web development has undergone substantial changes, reshaping the way people interact with the internet and redefining industry standards.

One of the most substantial changes in web development is the advent of responsive web design with the help of frameworks for both front-end and back-end development. In the past, websites were designed with static layouts that could only be viewed on desktop computers.

Websites now are designed with certain technology stacks such as MEAN stack, the MERN stack or the LAMP stack. Read on to know more about these technical acronyms and the ins and outs of each.

MEAN and the MERN Stack

Both the MEAN and the MERN stack have 3 technologies in common with one differentiator, the front-end framework. It is Angular.js for the MEAN stack and React.js for the MERN stack. Let us talk about all the common technologies that both these stacks use, and then dive into the differentiator.

M for MongoDB

MongoDB is a widely used document-oriented NoSQL database system that has gained immense popularity in recent years. It is an open-source, cross-platform database that is designed to store and manage large volumes of unstructured data in BSON format, a binary representation of JSON (JavaScript Object Notation) documents.

This data format supports various data types, including strings, integers, boolean, dates, and arrays, and provides significant advantages over traditional databases, such as easy storage and retrieval of complex data types, as well as faster data access.

MongoDB also offers high scalability and flexibility, allowing it to be easily scaled across multiple servers to handle large volumes of data, making it a powerful and convenient tool for developers.

E for Express.js

Express.js, also known simply as Express, is a popular open-source web application framework for Node.js, a runtime environment for executing JavaScript code outside of a web browser.

Express.js is known for its simplicity, ease of use, and flexibility. It offers a lightweight core that can be easily extended with additional features and plugins. With its flexible routing system, a full stack developer can easily define and configure routes for handling different HTTP requests, allowing easy rendering of dynamic content.

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.

Conclusion

The course also offers guaranteed job interviews. So without any further delay enrol yourself in this course to bag all the lucrative opportunities. 

Data serves as the root cause for modern technological structures. It means that it also requires adequate storage and management. After all, data is here to stay, which can bring in several problems. We must assign them to different categories to understand how effectively we can solve each problem.

This is where relational and non-relational databases come into the picture. These databases are equipped with robust solutions that help carefully organise, access, and extract data. 

Whether you’re looking for a place to store simple or complex models or assign data to each category, databases can be a handy solution.

This blog will look into the pros, cons, and examples of the two most common databases. We will also examine the standard features and urge our readers to choose what’s best suited for their project. 

Additionally, we will see how a full stack development course can help us understand databases. Let’s get started!

What are Relational and Non-Relational Databases? 

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.
