Caveat

Due to the nature of SimpleDB, SimpleJPA is a subset of the features of the full JPA spec and may never become a full implementation. SimpleDB is not your dad's relational database. Then why base this on JPA you might ask? Because JPA is a very nice, well thought out specification that is based on real world use (ie: Hibernate). Most importantly are the JPA annotations that make defining persistence on your objects easy.
