Database for wordpress

I have asked this question in other places and do not know if I am asking the right people. I have had no responses at all so I will try here.

I have a database for autombile listings. See sample at http://midgeorgiatruckwanted.com/usedcars

I want to use this same database inside wordpress, but I do not even know where to begin. Is this even possible? What about framing it to a page or something like this?
