Top Technologies to understand Like a Freelance Java Backend Developer

Java is really a programming language broadly employed for web applications and mobile phone applications because of its sturdiness and scalability. Java backend developers are very popular within the freelance market and also the IT industry. The interest in Java programmers continuously grow with time.

Here are the top technologies that you ought to learn like a freelance Java backend developer:

Spring Framework

The Spring Framework is definitely an open-source framework that gives enterprise database integration support for Java web applications. It’s utilized by greater than 3 million developers and it has been downloaded greater than 40 million occasions.

Spring provides support for dependency injection and aspect-oriented programming (AOP). Additionally, it includes JUnit testing, caching, transaction management, and web integration support.

Spring Data JPA

Spring Data JPA is really a library that gives CRUD functionality for the Spring Data repositories. It’s a different one of individuals technologies that help you to get up to date with Spring rapidly and simply.

The primary objective of this project is to supply a complete solution for mapping from Java objects to database tables and the other way around without requiring additional XML configuration. To do this goal, it uses the conventional Java Persistence API (JPA) underneath the hood, so it seems sensible to check out it if you are wondering much more about JPA itself.

Node.js

Node.js is really a JavaScript runtime atmosphere built by Ryan Dahl in ’09. It had been created for building fast network applications using non-blocking I/O APIs in line with the V8 engine in the Google Chrome browser.

It enables backend developers to construct scalable network programs that may handle a large number of concurrent connections at any time with no the process of scalability or performance issues since it uses a celebration looping model rather from the traditional threading model, that makes it highly scalable.

Hibernate

Hibernate is definitely an object-relational mapping (ORM) framework for Java that simplifies data persistence for Java applications through the elimination of direct SQL statements inside your code. An ORM framework uses an abstraction layer to map objects inside your code to tables on the database server, enabling you to communicate with individuals objects as though these were a part of your application’s storage.

This will make it simple to perform queries against databases without writing complex SQL statements or focusing on how information is kept in relational databases.

Summing-up

With regards to backend development, multiple programming languages and tools can be found. Like a backend developer you need to keep close track of what’s sought after and trending. This allows you to differentiate themselves from your competition. Continue learning, practising, and building systems because networking is paramount to success inside your professional career.
