Glad to hear it's working!

I work with databases, so I figured the best way to learn Z, Latex, Fuzz and Z with databases all together is by rewriting the specifications for practice. If you could point me toward better sources or similar researches I would be grateful.

For learning Z, I would recommend the book Using Z, freely available in electronic form:

In fact, there are a number of texts listed on the Wikipedia page:

I'm sure there are lots of database-related case studies - hopefully others can give you some references.  One I do know of, relating to security levels, is described here:
http://www.lemma-one.com/ProofPower/fef/fef.html
(which actually uses HOL but in a Z-like way).
