Robert,
Let me explain how the Secant EES/EJB product does what you have asked
below. We provided CMP as part of EES/EJB.
<vendor>
With our product you start with an object model defining all of your
classes, including session beans, entity beans, sub-objects, etc. You can
specify this model in UML using Rose or it can be specified using our Object
Description Language(ODL). In either case, as a part of the specification,
you provide implementation details describing how you would like the model
persisted into relational tables. This class-to-database mapping
specification is very flexible, allowing various subsetting and supersetting
techniques all under your control.
>From these details, we are able to initially create the DDL for the
database, and also create a meta-data description file which is used by our
Persistent Object Service & EJB Container at runtime in conducting the
mapping based on your specification.
BTW, we are also able to go the reverse direction. Start with an existing
database, derive the beginnings of an object model, etc.
</vendor>
Hope that helps.
