Encapsulation of the persistence mechanism. You should only call the save, delete, restore methods of your persistent objects and the Persistence Layer will automatically perform an action with your database. Multiple object actions. You can retrieve and delete multiple objects at once. Associations support. When you save delete or update any object you can do the same action with associated objects. Inheritance support. Makes possible to map an inheritance tree to a database schema. Transactions support. You can combine several actions into one transaction and commit or rollback it as a single action. Multiple database support. Different objects can be mapped to different databases. Now only support MsAccess and MsSQLServer Optimistic and pessimistic locking support
