The Hibernate is an object-oriented relational mapping tool that is used for Java programming language. It provides high-performance data queries as well as retrieval facilities and takes care of the mapping. Hibernate is used for overcoming the limitations of JDBC. This gives an abstraction layer which means the developer no need to implement does the implementation internally for use. It is open-source, lightweight and doesn’t require POJI and POJO model programming. You can use this in Auto DDL operations and Auto Primary Key generation as well.
