An Art Museum needs to keep track of its artwork and exhibitions. The museum has a collection of artwork. Each piece of art has a unique id [ArtID], an artist, year and title. Artwork is categorized by type. There are two types, paintings and sculptures. Paintings have a paintType and style. Sculptures have a material, height and weight. Artwork is frequently shown in exhibitions. Each exhibition has a unique name, startDate, endDate. A listing of the artwork displayed at an exhibition is also retained. Below is an E-R diagram for a database to help the Art Museum.

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.…
calculate_new_balance Given a starting balance (a number), and a list of transaction tuples, calculate the final balance for an account. Transaction tuples are of the shape ("description", amount, "withdrawal") , or ("description", amount, "deposit"). The last entry in the tuple will be either "withdrawal" or "deposit". Every withdrawal decreases the balance of the account by the specified amount, and every deposit increases the balance. The return value is the new account balance, as a number. (which could be negative) Sample calls should look like: >>> calculate_new_balance(100, [("payday", 20, "deposit"), ("new shoes", 50, "withdrawal"), ("illicit winnings", 200, "deposit")])270>>> calculate_new_balance(100, [])100
