22. REA Diagram with Cardinality (20 marks)
Assume that you own five apartments in Dongqian Lake. Your business provides holiday apartment rental to people who take short-term holidays in Dongqian Lake. This is your main source of income. You want to design and build a database to keep track of your business. The following describes how your business is running.
The first thing that happens in your business is that one customer reserves a holiday home (i.e. one of your five apartments) for his/her vacation with families and friends. Reservations are made for specific days, and each day is associated with a specific cost. The entire rental must be paid at the same time of reservation. Customers then come to the lake, stay in the holiday home and enjoy their holiday. Feedback and satisfaction rating forms are available in the apartment; customers can fill out the form. if they would like to or if they have any complaints when staying in the holiday home. After customers leave the apartment, one of your employees checks the apartment and identifies anything that has been damaged. You keep a record of the conditions of each apartment after each rental and an estimate of the repair costs after each rental. You have three employees who maintain, clean and check the condition of the apartments.
Note: assume that there are no cancellation cases.
Required:
Given the above brief overview, draw an E-R Diagram for your business. Remember to use the REA methodology of identifying resources, events and agents. Your diagram should also include cardinalities. Also, briefly describe the three steps involved in developing the REA diagram.
