I am trying to build a database for my son and I. We started a business renting software. We have multiple copies of some software. We need a database that tracks sales of the software my son owns as well as the software I own. I need to be able to separate the software by adding the last 5 of the activation key for the software due to having multiple copies of the same software. My son owns some and I own some. So when it comes time to pay out and to dived the money based on whos software rented. The software is rented daily, multiple days, weekly, monthly. The price changes based on the days and demand. I want to be able to have reports for time periods, on software each of us owns and so on. Sorry for all the information. I need help
