The benefits of using the framework, Hibernate caching

Benefits of using frameworks

1) Improve development efficiency: including development and maintenance

2) Change in requirements: Reduce the amount of changes

3) Decoupling architecture

Hibernate cache

First-level cache (session cache and Sessionfactory's built-in cache), level two cache (sessionfactory external cache).

The built-in cache contains mapping metadata and predefined SQL statements, which are read-only, and external caches, whose data is a copy of the database data, and the media can be either memory or hard disk.
