Sure, there is a sea of literature on that. Just go to your favourite search engine and look for information on "deductive databases".

It would be more helpful if you would explain what you *can* do and what you *do* want. :-) Do you have to use a certain relational database or could you switch to a deductive database? Do you really want to derive information or are we just talking about elaborate database constraints here? It is hard to help you if you are not more specific about what your problem is.

I haven't read the book but I am told that he doesn't go into details such as the implementation. He presents a nice way to organize and categorize your bussiness rules (if you want to call them that way) and then ... nothing. Thats it.
