Apache Torque is an object-relational mapper for java. In other words, Torque
lets you access and manipulate data in a relational database
using java objects.
Unlike most other object-relational mappers, Torque does not use
reflection to access user-provided classes, but it generates the
necessary classes (including the Data Objects) from an XML schema
describing the database layout (which can either be written by hand
or generated from an existing database).
The XML schema can also be used to generate and execute a SQL script
which creates all the tables in the database.
As Torque hides database-specific implementation details,
Torque makes an application independent of a specific database
if no exotic features of the database are used.
Usage of autogeneration eases the customization of the database layer,
as you can override the autogenerated methods and thus easily change
their behaviour.
Torque was developed as part of the
