Question 3. 100 points



The Rocky Mountain Athletic Club is a fitness and sports club in Denver. The club has seven indoor clay courts, and five outdoor hard courts. The club is open daily from 6:.00 am to 10:00 pm.

Here is the process for new member admittance. When filling out the membership application, you provide information including name, address, city, home phone, cell phone, and e-mail address, membership type and payment information. Applications are then reviewed by the club manager.  Once approved, new members are given a unique membership number.

When playing tennis, the club encourages its members to join teams, although each member can only belong to one team. When joining a team, the member contacts a receptionist either by phone or at the club, who will follow the correct registration procedure.

A court session (one hour long) can be reserved by phone or online by either a team leader or by an individual member. Pricing for a session varies according to the time and day of the week. A reservation can be cancelled by the person who booked it. In such a case, the session can be  rebooked.   Session records are created by the manager a few weeks in advance.   This allows members to reserve a court weeks in advance. Each court reservation is identified by its date, time and court number. Session records are deleted after six months.
