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.…

In addition to a variable's name, its "type" and "extra characteristics" must be specified. That is to say, apart from its data type, every variable has its own distinct characteristics. If you could elaborate on the idea so that we could better clarify the terms, that would be great.

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

SQL Language Question

PATHS is a table that contains information about paths on a number line. The structure of PATHS is as follows, where x1 and x2 represent that there is a path from Coordinate x1 to Coordinate x2 (You can't move from Coordinate x2 to Coordinate x1 ). NAME ΤΥΡE NULLABLE X1 INT FALSE X2 INT FALSE Problem Please write an SQL statement that returns the beginning and end point of each path in PATHS . Sort them by the value of the beginning point in ascending order. Constraints • In the case where a direct path from Coordinate a to Coordinate b is available, no path from Coordinate b to Coordinate a will be given. |x1-x2| = 1 • No path will overlap with one another. Example Suppose that PATHS is as follows: x1 x2 1 2 2 3 4 7 7 6 This table can be visualized as follows: START END END START 7 8. 9 Therefore, your SQL statement must return the following: start end 1 4 8 6
