The manager of a company dinner club would like to have an information system that assists him to plan the meals and to keep track of who attends the dinners, and so on. Because the manager is not an IS expert, the following table is used to store the information. As a member can attend many dinners and a member will not attend more than 1 dinner on the same date, the primary key of the following table is Member Num + Dinner Num. Dinners can have many courses, from one-course dinner to as many 3) courses as the chef desired.
