Hibernate in Java is an Object-Relational Mapping (ORM) tool that provides a framework for object-oriented mapping models to relational databases for web applications. One of Hibernate’s primary functions is to map entities in a Java class to tables in a database and to map Java data types to SQL data types. Hibernate can also be used for queries or retrieving data. It absolves the developer from having to manage the database manually. In this blog, we will go over what is Hibernate in Java and its advantages. To learn more about Hibernate, join the Hibernate Training in Chennai at FITA Academy, which offers certification training and placement support.
What is Hibernate in Java?
Hibernate in Java is an Object-Relational Mapping (ORM) framework created in 2001 by Gavin King. It makes the interaction between a database and the Java application being developed easier. It is a powerful and lightweight ORM tool. Another important aspect is that this is a high-performance open-source tool. Hibernate is a powerful object-relational persistence and query service for Java applications that implements Java Persistence API specifications.
Why do we Need Hibernate in Java?
Writing the same lines of code in your application repeatedly to retrieve data from a database can be tiresome and irritating. Furthermore, switching from one database to another, implementing oops with JDBC, and creating associations between database tables require significant effort and rework if not done with the Hibernate framework. As previously stated, Java Hibernate is an ORM tool that assists in resolving all issues encountered using JDBC for database connectivity.

In comparison to JDBC, Hibernate will connect itself with the database. Hibernate uses Hibernate Query Language, or HQL, to execute queries. After executing the queries, Hibernate will map the results to their respective application layers. This mapping produces objects entirely based on the properties specified in Hibernate’s configuration XML file. A session not only assists an application in establishing a connection with the database, but it also works to save and retrieve the persistent object in Hibernate. Session factory allows you to create an instance of a session and use it; however, each database should only have one session factory.
Advantages of Java Hibernate
Hibernate in Java implements the architectural design pattern of ORM just as similar to other implementations. Now we’ll list down the advantages of using Hibernate in Java.
- Lightweight and open-source – Because it is lightweight and open-source, it is easy to use and efficient.
- Improved performance – Using cache memory helps in quick performance.
- Database Independence – Being database-independent allows it to work with various databases.
- Automatic table creation saves us from having to create tables manually.
- It handles mapping Java classes to databases using XML files without needing any code.
- We can store and retrieve data directly from the database using simple APIs.
- It does not require an application server to function.
- Smart fetching strategies reduce database access.
- It allows for simple data querying.
