Oracle Application Server TopLink Unit of Work Primer

Overview Oracle Application Server TopLink (TopLink) is an advanced object-to-relational persistence architecture, suitable for a wide range of Java 2 Enterprise Edition (J2EE) and Java applications that store persistent data in a relational database. TopLink changes persistent data using a transaction pattern. A transaction is a set of operations (adds, deletes, and changes) that either succeeds or fails as a single unit. If any one operation fails, no changes are made to the underlying relational database or the persistent objects or beans stored in the shared cache. Transactions in TopLink are implemented by the Unit of Work object. Using the Unit of Work, one can transactionally modify objects directly or by way of a J2EE external transaction controller (such as JTA).
