Itcan 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.
