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. If you need to make assumptions, make sure they are reasonable assumptions. Questions Figure 2-8 shows data that Garden Glory collects about properties and services.
