Please create an entity relationship diagram (ERD) using Crow's foot notation to indicate entities, relationships, connectives, and participations (use Visio if possible).

AT&T 1:41 PM 81% Database System - Design, Implementation... Chapter4 Entity Relationship (ER) Modeling 161 a. Create a Crow's Foot notation ERD to support LOST operations, b. The operations provided state that is possible for a guide to lead an outing of a tour even if the guide is not officially qualified to lead outings of that tour. Imagine that the business rules instead specified that a guide is never, under any circumstance, allowed to lead an outing unless he or she is qualified to lead outings of that tour. How could the data model in Part a. be modified to enforce this new constraint You can use the following cases and additional problems from the Instructor Online Com- panion as the basis for class projects. These problems ilustrate the challenge of translating a description of operations into a set of business rules that will define the components for an ERD you can implement successfully. These problems can also be used as the basis for discussions about the components and contents of a proper description of operations. If you want to create databases that can be successfully implemented, you must learn to separate the generic background material from the details that directly affect database design. You must also keep in mind that many constraints cannot be incorporated into the database design; instead, such constraints are handled by the application software. Cases 11. The administrators of Tiny College are so pleased with your design and impleme tation of their student registration an the design to include the database for their motor vehicle pool. A brief description of operations follows: d trackin g system that they want you to expand Faculty members may use the vehicles owned by Tiny College for officially sand- tioned travel. For example, the vehicles may be used by faculty members to travel to off-campus learning centers, to travel to locations at which research papers are presented, to transport students to officially sanctioned locations, and to travel for public service purposes. The vehicles used for such purposes are managed by Tiny College's Travel Far But Slowly (TFBS) Center Using reservation forms, each department can reserve vehicles for its faculty, who are responsible for filling out the appropriate trip completion form at the end of a trip. The reservation form includes the expected departure date, vehicle type required, destination, and name of the authorized faculty member. The faculty member who picks up a vehide must sign a checkout form to log out the vehicle and pick up a trip completion form. (The TFBS emp for use also signs the checkout form.) The faculty members trip completion form includes the faculty members identification code, the vehicles identification, the odometer readings at the start and end of the trip, maintenance complaints (if any). gallons of fuel purchased (if any), and the Tiny College credit card number used to pay for the fuel. If fuel is purchased, the credit card receipt must be stapled to the trip completion form Upon receipt of the trip completion form, the faculty mem ber's department is billed at a mileage rate based on the vehicle type used: sedan, station wagon, panel truck, minivan, or minibus. (Hin: Do not use more entities than are necessary. Remember the difference between attributes and entities!) employee who releases the vehicle 187 of 818 162 Part 2 Design Concepts All vehicle maintenance is performed by TFBS. Each time a vehicle requires maintenance, a maintenance log entry is completed on a prenumbered mainte- nance log form The maintenance log form includes the vehicle identification, brief description of the type of maintenance required, initial log entry date, date the maintenance was completed, and name of the mechanic who released the vehicle back into service. (Only mechanics who have an inspection authorization may release a vehicle back into service.) As soon as the log form has been initiated, the log form's number is transferred to a maintenance detail form; the log forms number is also forwarded to the parts department manager, who fills out a parts usage form on which the maintenance log number is recorded. The maintenance detail form contains separate lines for each maintenance item performed, for the parts used, and for identification of the mechanic who performed the maintenance. When al maintenance items have been completed, the maintenance detail form is stapled to the maintenance log form, the maintenance log form's completion date is filled out, and the mechanic who releases the vehicle back into service signs the form. The stapled forms are then filed, to be used later as the source for various maintenance reports. TEBS maintains a parts inventory, including oil, oil filters, air filters, and belts of various types. The parts inventory is checked daily to monitor parts usage and to reorder parts that reach the "minimum quantity on hand" level. To track parts usage, the parts manager requires each mechanic to sign out the parts that are used to perform each vehicles maintenance, the parts manager records the main tenance log number under which the part is used. .Each month TFBS issues a set of reports. The reports include the mileage driver by vehicle, by department, and by faculty members within a department. In addi tion, various revenue reports are generated by vehicle and department. A detailed parts usage report is also filed each month. Finally, a vehicle maintenance sum- mary is created each month. Given that brief summary of operations, draw the appropriate (and fully labeled) ERD. Use the Crow's foot methodology to indicate entities, relationships, connectiv- ities, and participations. 12. During peak periods, Temporary Employment Corporation (TEC) places temporary he business: in companies. TEC's manager gives yo u the following description oft TEC has a file of candidates who are willing to work. Any candidate who has worked before has a specific job history. (Naturally, no job history exists if the candidate has never worked.) Each time the candidate works, one additional job history record is created Each candidate has earned several qualifications. Each qualification may be earned by more than one candidate. (For example, more than one candidate may have earned a Bachelor of Business Administration degree or a Microsoft Net work Certification, and clearly a candidate may have earned both a BBA and a Microsoft Network Certification.) .TEC offers courses to help candidates improve their qualifications. Every course develops one specific qualification; however, TEC does not offer a course for every qualification. Some qualifications are developed through multi ple courses. Some courses cover advanced topics that require specific qualifications as pre- requisites. Some courses cover basic topics that do not require any prerequisite AT&T 1:41 PM 81% Database System - Design, Implementation... Chapter4 Entity Relationship (ER) Modeling 161 a.
