Faster development. Full flexibilityFull freedom on class design. O/R Broker does not place any limitations on how you design your classes. No restrictions whatsoever. You write the SQL. This allows you to hand tune any query and from personal experience, is as fast (if not faster) than configuring some obscure XML file. You write the query-to-object mapping code in Scala (or Java). No tired XML mapping needed. SQL can be in code or, preferably, in simple text files, ready for editing and optimizations if needed. SQL can be dynamic through either Velocity or FreeMarker template engine syntax. Both are supported, but none are required. Dealing with new database schema, legacy schema, JavaBeans, or immutable classes? All possible, full flexibility.
