What is Hibernate?
Hibernate is a Java framework used to develop applications for connecting with the database. More precisely, it is an open-source and high-performance Object Relational Mapping tool licensed under GNU Lesser General Public License (LGPL). It lets mapping of the Java domain object with database tables and vice versa. By that, the business logic is capable to reach and manipulate database entities through Java objects. Further, it also helps in speeding up the entire development process by taking control of all aspects such as automatic primary key generation, transaction management, managing database connections, and so on. Hibernate query language is a SQL’s object-oriented version and supports in generating database independent queries. Executing demands of JPA (Java Persistence API) for data persistence was achieved faster using Hibernate. It also supports fetching data from multiple data sources.
