POEM (Persistent Object Engine for Melati)

POEM provides:

• generated java classes to support Object Releational Mapping (ORM)
• a richer Domain Specific Language (DSL) to descibe database structure which can be generated from existing databases or generate new from scratch.
• an API which enables the database to be seen as a collection of Java objects, via a (genuinely!) easy-to-use transparent persistence layer on top of JDBC.
• a low level security model allowing restrictions to be placed on tables, rows and fields.
• a three way unification of jdbc, sql and java metadata.
• a type system which enables string fields to be polymorphic.
• a transaction system which enables insulated sessions.
• rich metadata which enables object rendering.
