Hibernate not only takes care of the mapping from Java classes to database tables (and from Java data
types to SQL data types), but also provides data query and retrieval facilities. It can significantly reduce
development time otherwise spent with manual data handling in SQL and JDBC. Hibernate’s design goal is to
relieve the developer from 95% of common data persistence-related programming tasks by eliminating the
need for manual, hand-crafted data processing using SQL and JDBC. However, unlike many other
persistence solutions, Hibernate does not hide the power of SQL from you and guarantees that your
investment in relational technology and knowledge is as valid as always.
