Projects / Hibernate


Hibernate is a powerful, high performance object/relational persistence and query service for Java. It lets you develop persistent objects following common Java idiom, including composition, association, inheritance, polymorphism, and the Java collections framework. To allow a rapid build procedure, Hibernate rejects the use of code generation or bytecode processing. Instead, runtime reflection is used and SQL generation occurs at system startup time. It supports Oracle, DB2, MySQL, PostgreSQL, Sybase, Interbase, Microsoft SQL Server, Mckoi SQL, Progress, SAP DB, and HypersonicSQL.
