Rule Base Programming in Delphi (Expert System?)

[FaNIX]

Hi to everyone,

I was wondering if someone could guide me in the right direction with my current satiation:

I'm developing a banking application, which does all the basic banking transactions, like deposits, withdraws etc... Now the banking industry is a very complicated market, which involves a lot of product and clients rules, that needs to be executed to reach a decision. A decision can either be TRUE(YES)/FALSE(NO) or a Value being returned.

This is your typical business rule scenario. I did a course in Expert systems, so I know the principles of an expert system would work 100% with my current senario, but I can't seem to find a 3rd party expert system for delphi?

It's not essential that I use an expert system, maybe another algorithm that anyone can suggest?

PS: I had a look at www.riversoftavg.com, but it's too complicated, it includes to much stuff, I want it as basic as it comes.
