org.apache.empire.db.codegen.CodeGenWriter

This is the entry class for generating the java persistence model based on a database schema. It uses the Empire DB open-source framework to build a java persistence layer for an application. The Apache Velocity template engine is used to create the output interfaces and classes.

The Empire DB framework doesn't try to hide the underlying database and data model but instead embraces its power by modeling it within java. The result is a persistence layer that uses a more "object-oriented, type safe" SQL to access persistent data.

NOTE: THIS VERSION HAS SEVERE RESTRICTIONS:

Only tables are currently modeled (we'll add views to a later version).
Table indexes are not yet modeled (exception is primary key). Again, this will be added to later editions.
It is assumed that each table has a single INTEGER auto-generated primary key column that has the same name for all tables.
It is assumed that each table has a single TIMESTAMP optimistic locking column that has the same name for all tables.
