Hibernate

What is Hibernate?

Hibernate is an open-source object-relational mapping (ORM) tool that provides a framework to map object-oriented domain models to relational databases for web applications.

The Hibernate ORM framework guides mapping Java classes to database tables and Java data types to SQL data types and provides querying and retrieval.

How does Hibernate works?

Hibernate is an open-source Object-Relational Persistence and Query service for any Java Application. Hibernate maps Java classes to database tables and from Java data types to SQL data types and relieves the developer from most common data persistence related programming tasks.

Hibernate sits between traditional Java objects and a database server to handle all the works in persisting those objects based on the appropriate O/R mechanisms and patterns.

Why use Hibernate?

Hibernate reduces lines of code by maintaining object-table mapping itself and returns results to applications in form of Java objects.

Benefits of Hibernate

• Hibernate is an Object/Relational Mapping solution for Java programming language. The term Object Relational Mapping refers to the process of mapping data from java object model representation to a relational database representation (and vice versa).

• Hibernate framework takes care of mapping from Java classes to database tables (and from Java data types mapping to SQL data types), and also provides data queries and retrieval features using different hibernate APIs.

• Hibernate is design in such a way that it makes developer life easier from common data persistence-related programming tasks by eliminating the need for manual or hand-written data processing using SQL and JDBC.

• Hibernate does not hide the power of SQL and guarantees that your effort in relational technology and knowledge is always as valid.
