This O-R Java persistence framework supplies the classes that developers use to:

• Connect to the database

• Write objects to the database

• Perform queries that return objects from the database

• Create transactions that synchronize changes to the object model and database

The TopLink runtime library manages all database interactions and provides powerful, flexible features that enable developers to focus on solving business problems, not building the database infrastructure.

The TopLink runtime library also provides advanced features such as object caching to improve application performance and the TopLink Query Framework to simplify database queries.
