HELP with Zoological database

[buys at pttrnl.nl]

At the moment I am studying the possibilities for a universal database 
structure for the Mollusca collection of the National Natural History 
Museum of the Leiden University in the Netherlands.
Does anyone have experience with the design of databases for the registration
of zoological data? Does anyone have a sample data-dictionary?
All responses are most welcome.

Regards,

Jan-Paul Buys
