# Unit of Work Sessions

Previous

Next

The unit of work ensures that the client edits objects in a separate object transaction space. This feature lets clients perform object transactions in parallel. When transactions are committed, the unit of work makes any required changes in the database, and then merges the changes into the shared TopLink session cache. The modified objects are then available to all other users.

For information on creating, configuring, and using a unit of work, see "Understanding TopLink Transactions".
