New: This wiki page is no longer to be considered the main homepage of MetaModel! This serves as a community place for documentation collaboration and ad hoc writing of snippets and small pieces of information.

Please be sure to visit the new official MetaModel website at http://metamodel.eobjects.org

It is one of the important goals of MetaModel to be compliant with as many databases and datastores as possible! We ensure a broad compliance by several initiatives:

  • A broad integration test suite.
  • Extensive but fault-tolerant use of the Java DataBase Connectivity (JDBC) specification.
  • Use of uniform SQL-99 compliant queries.

Supported databases

Below is a list of databases that we support and continuously test for all our functionality. If you experience any issues with a supported database we will be able to help you, so post your questions and we will deal with it promptly:

Database Version JDBC Driver Compliancy

PostgreSQL 8+ PostgreSQL JDBC Driver Fully compliant
Oracle 10g SQLJ/JDBC Fully compliant

  • Ingres (Look for ticket #225 for support progress)

None known yet. If you try out MetaModel and experience problems, let us know and we will see what we can do!
