Spring Breaks R Us (SBRU) is an online travel service that books spring break trips to resorts for college students. Students have booked spring break trips for decades, but changes in technology have transformed the travel business in recent years. SBRU moved away from having campus reps with posted fliers and moved to the Web early on. The basic idea is to get a group of students to book a room at a resort for one of the traditional spring break weeks. SBRU contracts with dozens of resorts in key spring break destinations like Florida, Texas, the Caribbean, and Mexico. Its Website shows information on each resort and includes prices, available rooms, and special features. Students can research and book a room, enter contract information, and pay deposits and final payments through the system. SBRU provides updated booking information, resort information updates, and travel information for booked students when they log into the site. The resorts also need access to information from SBRU. They need to know about their bookings for each week, the room types that are booked, and so forth. Before the spring break booking season starts, they need to enter information on their resorts, including prices and special features. Resorts need to be paid by SBRU for the bookings, and they need to be able to report and collect for damages caused by spring breakers during their stay.

PART 1 Consider the SBRU Social Networking subsystem, and the potential domain classes that might be involved in this subsystem. For example, there would need to be information about a traveler attending a resort for a particular week. The traveler would be assigned to a room along with roommates but might also be connected to other friends. There might be different interests or hobbies a traveler can associate with in hopes of connecting to others. The resort has many locations where a traveler might be hanging out at any given time, and a traveler can note whether the location is liked. People might schedule a party at a location and invite specific friends.

1. For the Social Networking subsystem as described here, list the domain classes and their attributes that should be included in the Social Networking subsystem. Be creative and add those you think should be included to make the system useful and appealing.

2. Based on the domain classes you identified, draw a domain model class diagram showing domain classes with attributes and associations with multiplicity.

PART 2 The Spring Breaks R Us Travel Service system has many use cases and domain classes, which you identified previously.

1. For the use case Add New Resort, write a fully developed use case description and draw an SSD. Review the classes that are associated with a resort in the domain model to understand the flow of activities and repetition involved.

2. For the use case Book a Reservation, write a fully developed use case description and draw an SSD. Review the classes that are associated with a reservation in the domain model to understand the flow of activities and repetition involved.

3. Draw an activity diagram to show the flow of activities for the use case Add a New Resort.

4. Do a CRUD analysis based on the domain model you built in the previous section and the use cases you have defined thus far.
