Re: Generate middleware from database design?

If we presume that the question means that the middleware encompasses databases but no
functionality of any sort, then the
interpretation of the question becomes :- "How do we define one single view of a variety of data sources in a heterogeneous situation so that enterprise data integration can be achieved seamlessly and in real-time."

This leads to the question of Data Dictionaries and standards for table-driven data retrieval and integration.

I guess an answer could be obtained by looking at a few commercial products and establishing what kind of language or specification would be appropriate to map on to each product to specify the middle tier.

Sounds interesting so maybe I'll take the time to do something about it.
