I have an excel spreadsheet with thousands of addresses, along with other information that I would like to be converted into a well thought-out Access database. I have only a basic knowledge of Access and what it is capable of doing, so I will need some suggestions of how best to structure it. The most important feature will be for it to combine duplicate addresses so that I do not repeat mailing to them, while still tracking the multiple campaigns that have produced that address as a lead. I will want to be able to easily import in excel spreadsheets and also to enter addresses one at a time via a form. I will also want reports that are easily generated based on campaign or mailing dates.
