I would treat this effort as a class and offer up the following syllabus:
David Hay’s Conventions of Thought, Data Model Patterns
Richard Barker's Entity Modelling
Some book on 3rd order predicate calculus—need to find my as a reference
Installed Local Database (pick one) with SQL only tool (no TOAD et al)
Definitely agree on the recommendation for Hay's book.
I agree also on the "(pick one)" recommendation for installing a local db. In fact, one thing I need to do is branch out some and play with MySQL and Postgres. Currently, my only real exposure is MS SQL and Oracle, so it would be good to get some hands on with the other players, too.
Thanks for the comments and recommendations!
