One solution - put the protection into the contract. Model leaks out, you get to sue the customer.

Otherwise, realize that the data dictionary (which is different from, albeit related to, the data model) is the primary tool the DBA has to ensuring your product can be secured and tuned.

The DBAs are actually on your side. Why tick them off? /Hans
