This is the core library for Active Objects. It is generic and can be embedded in any environment.
As such it is generic and won't contain all connection pooling, etc.

/**
* Superinterface to all table name converters; designed to impose conventions
* upon the auto-conversion of class names to database tables. The idea
* behind this is to allow user-specified table name conventions and standards
* rather than always enforcing ActiveObjects's idea of "good naming".
*
* Every {@link EntityManager} contains a single table name converter which
* the entire library uses when performing operations. Any third-party code which
* interacts with tables directly should make use of this faculty. By using
* the table name converter even in ORM-external operations, the developers can
* control table names in a single location and ensure that the conventions
* need only be maintained in one spot.
