You have no idea? That can be interpreted many ways. If I were a computer that would mean to me that you need help with UI design, database design, how to connect to the database and the list goes on. I can only guess what you really need help with. When I'm roughing out a project I keep the output in mind. If in the end it's a report that needs to be viewed and or printed then that will be my guiding light. For me then there will be SQL statements to produce the report. So with that in mind I will mockup how the queries fit in the system. Design the database. Decide how to restrict what parts of the system are available to which ever group of users. Maybe a login will dictate which parts of the system are enabled or something like that. Get everything figured out. Then with your roadmap tackle the bits and pieces making sure to not add or take away anything from the ultimate goal. I saw an Access inventory template available once from Microsoft. Take a look at that to see how that system flows to get some ideas if you think you will benefit from it.
