I have started to create some access databases for private projects many times over the last 20+ years, but never really completed any of them. So I have some basic knowledge. I recently started a new job, and observe that we use excel for everything, including inventory managment and invoicing. I'd like to convert as many of the excel files as possible to access databases, and ideally, all of then in the same database. Now I am stuck on a few database design issues, and hope I can ask questions here that can move me forward. I will post my questions in the (hopefully correct.....) forums.
