Interface Connection

public interface Connection

Persistence technology agnostic connection interface. Connections are created by a DataSource.

Note that this interface uses the DataSource-Connection metaphor used by JDBC, but it is in no way linked to JDBC.

One way to look at a connection is as a Unit of Work [Fowler]: it provides commit and rollback methods to commit the changes to the persistent store or to undo them.
