Teneo 1.0.4 provides support for EclipseLink. The following sections explain the principal features it includes and give advice how they can be used for building model-based applications on top of relational databases.
Creating EclipseLink/JPA Mappings for EMF models
Three possibilities:
- Model-driven
- Meet-in-the-middle
- Schema-driven
Accessing EMF Models in Databases using the EclipseLink Resource
Teneo/EclipseLink provides a full implementation of EMF's Resource interface named EclipseLinkResourceImpl. It enables applications to load and save EMF models from or to relational databases and to manage their lifecycle directly through EMF's built-in persistence API, i.e. the ResourceSet interface. EclipseLinkResourceImpl represents an almost complete abstraction from JPA mappings and EclipseLink APIs and makes accessing models in databases, from an EMF point of view, as natural as loading or saving models from files.
