Forum OpenACS Q&A: Response to boring data model book suggestions?

Posted by John Sequeira on
"Data Model Patterns" by David C Hay is probably what you want.

It doesn't cover class scheduling,  but you can always look at the OpenACS source code for that.

Also,  "Object Models: Stategies, Patterns and Applications" has some interesting case studies.  It's no directly applicable to relational databases - more about the middle tier (OO layer),  but still worth a look.
