[EMF] How to persist to SQL/RDBMS/JDBC? [message #655625]

We are new to EMF (obviously Smile

). We are considering using EMF for a new app which needs to use an SQL backend for persistence.

We need some pointers on how to do the persistence in EMF to SQL/JDBC. The docs we have seen (including the EMF 2009 book) all talk about XML for persistence. No mention of how to use SQL/JDBC. Is there an existing URI and Resource class which support SQL/JDBC? If not, anybody have suggestions on how to implement?

Thanks.

You may want to try CDO, which is a 3 tier architecture for modeled applications, a model repository and arbitrary data backends (including support for O/R mapping):
