I am trying to compile 2 years of previous price lists which are in Excel files. We would have prices changes at the first of each month and sometimes 3-4 times thereafter during those months. I am trying to figure out how to design my tables so that I can query a certain model for a certian date and it would retrieve the price for that particular date. Although I plan to build a query to allow me to build the price sheet as we go forward, does anyone have a suggestion as to how to design my tables in order to import all of these Excel spreadsheets with the various models and different prices. This is for a motorcycle dealership.

Also, I will probably build this database in MS Access but later convert it and upload it to Azure.
