What is Torque? Torque is a persistence layer. Torque includes a generator to generate all the database resources required by your application and includes a runtime environment to run the generated classes. Torque was developed as part of the Turbine Framework. It is now decoupled and can be used by itself. Starting with version 2.2 Turbine uses the decoupled Torque. Torque's runtime environment includes everything you need to use the generated OM/Peer classes. It includes a jdbc connection pool.
