Exercise 1 Car Dealership Create an ERD for a car dealership. The dealership sells both new and used cars, and it operates a service facility. Base your design on the following business rules: A salesperson may sell many cars, but each car is sold by only one salesperson. A customer may buy many cars, but each car is bought by only one customer. A salesperson writes a single invoice for each car he or she sells. A customer gets an invoice for each car he or she buys. A customer may come in just to have his or her car serviced; that is, a customer need not buy a car to be classified as a customer. When a customer takes one or more cars in for repair or service, one service ticket is written for each car. The car dealership maintains a service history for each of the cars serviced. The service records are referenced by the car’s serial number. A car brought in for service can be worked on by many mechanics, and each mechanic may work on many cars. A car that is…
Complete questions 2-7 Note: Complete questions 2-7 in part B of the Garden Glory Project on p.129 and 130 of the textbook (8th edition). There may be more than one service performed at a property on a given date. Use this information when you answer questions. Comment on each question whether a given design is good and provide reasons for that. For example, the answer for Q1 is “This design is not appropriate because the designated Primary Key (PK) (PropertyName) in the table cannot determine some other attributes of the same table (e.g., ServiceDate, Description, Amount); in other words, the designated PK is not unique”. Your answers need to be specific and should clearly pinpoint the design problem with references to the relevant attributes in the table and the reason of violation. Any vague answer like “This design is bad because the PK is not good”, are wrong. Note that the foreign keys are italicized instead of dashed underlined. Clearly label answers for each question.…

WEEK 8 ASSIGNMENT create a star schema for the Bob's Fixit Group Case Study . The star schema needs to support the analysis or measurement of material price by suppliers, date, and jobs. Case Study Bob owns a small company called Bob’s Home repairs. He does the small home repair jobs that the large companies pass by. Need some woodwork or wood furniture fixed? Call Bob. Here is how the business works: Someone calls Bob and asks him to bid on a job. He drives over, looks at the situation, and gives them a bid. Sometimes it is an official looking bid by mail, and sometimes it is scribbled on notebook paper. He decides how long it will take to do the job (he bills by the hour), how much wood will be needed, any odds and ends that are unique to the job, and an overall price. He moves from job to job and bills customers as he finishes the work. Bob buys items and supplies from a variety of places, but he buys stuff only when it is needed for a particular project. A potential problem:…
