When should you use Hibernate in Java Project?

Hibernate is ORM framework which is open source and one of the most used ORM framework in Java. Most of the business application is using Hibernate for writing code for interacting with the database. Hibernate ORM framework is very flexible and it supports large number of database. You can use Oracle, MySQL, DB2 and any of supported databases with Hibernate. In this article we are discussing when developer should use the Hibernate framework in Java project.

Hibernate is used in the projects due to following reasons:

Fast Application Development

Hibernate takes the responsibility of generation of sql queries and running it against database to perform database access work. For example if you are writing code to saving data into database Hibernate will generate insert sql, generate appropriate sql query, set the data and execute query with database. It saves a lot of development time and increases developer productivity.

Developers familiar with Hibernate are very comfortable in writing code fast and they concentrate on the business logic rather than coding the JDBC code for data access. Hibernate also provides annotation support which makes developer life much easier.

Error Free application

Hibernate takes care of all the database access related functionality and it provides a tool to developer for writing error free database access layer. Database operations are performed without any error and saves lot of time.

Performance

Hibernate generates efficient sql queries and it also provide caching mechanism. Hibernate knows how to generate efficient query for a database operation, further developer can also provide their own native query.

Cross Database portability

Hibernate support almost all the relational databases and it provides portability across all these databases. You only have to change few configuration settings in xml file and your application will start working with another database server. For example you move your application from MySQL database to Oracle database or SQL Server database by just changing few dialect settings in Hibernate configuration. Hibernate provides portability across a list of many databases.

With JPA

If you have decided to use Java Persistence API in your project for writing data access layer for your application then the Hibernate is the best choice to use as Persistence Provider in the application. On the top you will be using the JPA api for performing database operations and internally Hibernate will work for you. You can use all the advanced features of Hibernate with JPA. JPA with Hibernate is the first tool of choice by developers around the world.

Community Support

Hibernate is used by large group of people and you will easily find solution of issue. You can also discuss your error/problem in many free groups and community will help you in solving your issue fast. There are vast materials on the internet which you can search and learn from it.

Hibernate is free software and it is distributed under  GNU Lesser General Public License 2.1, which means you can use it for open source and commercial applications without any recurring cost.

Many software components

Hibernate is also modular framework and it comes with many modules. These modules are independent and you can use any or some of the modules as per your requirement.

Caching Support

Hibernate provides primary and secondary level caching which increases the performance of the application. You can use Ehcahe or any other commercial cache for your application with Hibernate.
