Instructions Answer the following questions related to the Happy Cruise Lines company (refer to Minicase 1 on page 17). Each question should be answered using proper rules of grammar, punctuation, and spelling where appropriate. Background Happy Cruise Lines has several ships and a variety of cruise itineraries, each involving several ports-of-call. The company wants to maintain information on the sailors who currently work on each of its ships. It also wants to keep track of both its past and future cruises and of the passengers who sailed on the former and are booked on the latter. Each ship has at least one and, of course, normally many sailors on it. The unique identifier of each ship is its ship number. Other ship attributes include ship name, weight, year built, and passenger capacity. Each sailor has a unique sailor identification number, as well as a name, date-of-birth, and nationality. Some of the sailors are in supervisory positions, supervising several other sailors. Each sailor reports to just one supervisor. A cruise is identified by a unique cruise serial number. Other cruise descriptors include a sailing date, a return date, and a departure port (which is also the cruise's ending point.) Clearly, a cruise involves exactly one ship; over time a ship sails on many cruises, but there is a requirement to be able to list a new ship that has not as yet sailed on any cruises, at all. Each cruise stops at at least one and usually several ports-of-call, each of which is normally host to many cruises, over time. In addition, the company wants to maintain information about ports that it has not as yet used in its cruises but may use in the future. A port is identified by its name and the country that it is in. Other information about a port includes its population, whether a passport is required for the passengers to disembark there, and its current docking fee, which is assumed to be the same for all ships. Passenger information includes a unique passenger number, name, home address, nationality, and date-of-birth. A cruise typically has many passengers on it (certainly at least one). Hoping for return business, the company assumes that each passenger may have sailed on several of its cruises (and/or may be booked for a future cruise.) For a person to be of interest to the company, he or she must have sailed on or be booked on at least one of the company's cruises. The company wants to keep track of how much money each passenger paid for for will cruises. The company wants to keep track of how much money each passenger paid for for will pay for) each of their cruises, as well as their satisfaction rating of the cruise, if it has been completed. Problems 1. Draw an entity-relationship diagram that describes the Happy Cruise lines business environment using Microsoft Visio (or equivalent Entity Relationship modeling software) and the Crow's Foot Database Notation template. The deliverable should be the Visio diagram or a PDF of the diagram (if using equivalent software). (20 points) 2. Consider the following relational database for Happy Cruise Lines. It keeps track of ships, cruises, ports, and passengers. A "cruise" is a particular sailing of a ship on a particular date. For example, the seven-day journey of the ship Pride of Tampa that leaves on June 13,2003 , is a cruise. Note the following facts about this environment: - Both ship number and ship name are unique in the SHIP Relation. - A ship goes on many cruises over time. A cruise is associated with a single ship. - A port is identified by the combination of port name and country. - As indicated by the VISIT Relation, a cruise includes visits to several ports and a port is typically included in several cruises. - Both Passenger Number and Social Security Number are unique in the PASSENGER Relation. A particular person has a single Passenger Number that is used for all of the cruises that she takes. - The VOYAGE Relation indicates that a person can take many cruises and a cruise, of course, has many passengers.
