Ebean's Relational features
The goal of Ebean is not to hide the Relational Database. More than that the goal of Ebean is to promote the use of Relational features when they make most sense. The use of UpdateSql, CallableSql, FindByNative and MapBeans will sometimes provide a simpler and more efficient solution that an ORM/Bean solution.
It is the intention for Ebean to provide both ORM and Relational features in the one persistence layer. This gives the developers the ability to choose the approach that best solves their needs. Whats more these features are all designed to work together in the same transaction.
Whether you use these features is up to you but hopefully you find them a useful way to get the job done in a simple and transparent fashion.
