Beach Rentals $($BR$)$ maintains an inventory of rental houses near universities and leases those houses primarily to student

renters. This case describes their rental business process. BR agents$-$former marketing majors renowned for their fast$-$

talking and flamboyant lifestyles$-$work with potential renters and sign the rental contracts for BR$.$

BR tracks its houses by city, neighborhood, and distance from campus. BR assigns one specific BR agent to each

neighborhood to manage rentals for all houses in that neighborhood, but each BR agent may be assigned to multiple

neighborhoods. BR cashiers collect the rent and are bonded for security purposes. Because cashiers never become

agents $($or vice versa$),$ BR tracks BR cashiers separately from BR agents, although both are identified by employee

numbers.

BR sets rental rates to its student customers by considering such matters as number of bedrooms and age of the house.

Additionally, BR applies a monthly rental surcharge to each house that depends solely upon its neighborhood designation;

for example, upscale neighborhoods have higher surcharges and less desirable neighborhoods have lower surcharges.

The same surcharge applies for the life of the lease. Every house has a rental surcharge, and all houses in a particular

neighborhood have the same surcharge.

Prospective renters contact BR to inquire about renting a house. When a potential renter contacts BR$,$ a BR agent is

assigned to assist them. That BR agent remains the person's point of contact for as long as they continue to deal with

Beach Rentals. BR records information on each potential renter as soon as they contact BR to inquire about a house.

BR agents negotiate the rental contracts with the students. Each rental contract must last at least $6$ months, and $12-$month

contracts get a $5$ percent discount. BR also charges a damage fee that is due along with the first month's rent when the

rental contract is signed. The BR agent earns a $10$ percent commission on each rental contract, and BR tracks the year$-$to$-$

date $($YTD$)$ commission earned for each of the BR agents. Of course, the BR agents compete with one another to see who

earns the highest commissions, and BR fosters the competition by giving an annual award to its "best" agent.

When multiple students want to rent one house, BR requires that they designate the primary renter$-$the one who will be

responsible for paying the rent. However, BR also gathers information about all the other occupants of the house and

designates them as secondary renters. All the renters sign the rental contract, and BR assigns a unique renter number to

each occupant. The students may not change primary renter for the term of a contract. BR cashiers collect the rental

payments monthly from the primary renters. BR records information concerning employees, house owners, bank accounts,

cities, and neighborhoods in the database before the renters are involved in any events. Each neighborhood is located in

only one city, and houses are in only one neighborhood.
