Teneo supports a fully top-down model driven approach that generates EMF classes, default JPA mappings for those classes, and the database schema required to persist those classes from a single Ecore model. Ecore annotations can be used to customize the generated JPA mappings and relational schema.

Teneo also supports the meet-in-the-middle approach of mapping EMF classes to an existing relational schema. This enables the construction of model driven applications on top of existing or legacy databases. Teneo can be combined with the Dali JPA Tools for meet-in-the-middle development with Dali providing intelligent mapping assistance and validation against the target relational schema.

This session will combine slides and demos to illustrate both the design time and runtime functionality of Teneo and EclipseLink.

The following topics will be addressed in detail:

• Top-down/Model-driven development

• Meet-in-the-middle mapping

• Ecore JPA Annotations

• Idioms for mapping EMF with JPA

• Orphan Management

• EclipseLink OSGI JPA

• Performance

• A comparison of Teneo/EclipseLink with CDO
