Abstract
The largest part of an API that persists objects to a relational database ends up being the objectrelational mapping (ORM) component. The topic of ORM usually includes everything from how the object state is mapped to the database columns to how to issue queries across the objects. We are focusing this chapter primarily on how to define and map entity state to the database, emphasizing the simple manner in which it can be done.
