Ever stumbled upon the situation, that you have a great idea for a web-application but you just hate writing all those manager-classes that all contain the same functions for basic CRUD operations? I have.
PersistenceObjects is a persistence library for managing an application's model classes and their respective representations in the database. The basic idea is similiar to JavaEE's Hibernate. You describe your model, create the database and then you simply use the PersistenceObjects in your controller classes for all CRUD operations.
