You sound like you understand database, but I`m not sure what level of programming experience you`d have or what your knowledge domain would be; the entire internet or just businesses in your database. The parts you would need for a database search; SQL, HTML (preferrably ASP.Net), C# or VB. w3schools.com would be an option. I just want to caution you, though, of thinking only in terms of tasks the computer needs to do %26amp; programming that way. Read tutorials on object oriented programming so you account for all needed parts in your design. It saves a lot of redoing later. Think about programming more like rewiring a house, not just painting the walls. There`s a lot underneath.
