Muscles Health Club Database Requirements
The Muscles Health Club needs a database to keep track of its members, their personal trainers, and the fitness classes that they are taking.
Employees can act as personal trainers for members. However, only certified employees can act as personal trainers. A member can work with only one personal trainer at a time.
Members can take multiple fitness classes. Fitness classes are taught by employees who can teach multiple classes. Fitness classes are taught in one of the classrooms at one of Muscles Health Club's several locations.
Each fitness classroom is designed for a different type of class (e.g., spinning, aerobics, water aerobics, weight training, etc.). It is necessary to track what fitness classes are being held in each of the different Muscles Health Club locations. Draw the ER Diagram showing the relationships of the entities and their cardinalities.
