I am working on a solution that tracks customer's attendance and use of assigned space and I am trying to figure out the best way to to this. The requirement is that each customer has to use their assigned space a minimum of 6 hours per day, 20 days per month. I have a table that has all the customer information and I am creating a separate table to tack their attendance. My staff conducts two separate attendance check one in the morning and one in the afternoon. Does anyone have a suggestion on how best to configure this task?
