The Supply relation records instances of a Supplier supplying a Part for a Project. The schema for the database used in this question is as follows: ( primary keys are shown underlined, foreign keys in bold). SUPPLIER (SNo, SupplierName, City) PART (PNo, PartName, Weight) PROJECT (JobNo, JobName, StartYear, Country) SUPPLY (SNo, PNo, JobNo, Quantity) Provide relational algebra (NOT SQL) queries to find the following information. NOTE: You can use the symbols s, P, etc or the words ‘PROJECT’, ‘RESTRICT’ etc . do not need to try to make efficient queries – just correct ones. Where you use a join, always show the join condition. List the name of any part that was not used on a project that commenced in 2020. List the name of any part that has been supplied to all projects that commenced in 2020.
True or False : ___ Multiple Inheritance happens when a class has more than one sub-class. This problem can be observed in Programming Languages as well. ___ Given two relations named A and B, if we q-JOIN A and B, the maximum number of attributes in the result relation could be (the number of attributes of A) times(*) the number of attributes of B). ____ * in an SQL SELECT statement means “all the tuples”. ____ In relational algebra, Cartesian Product (X) can be implemented using the q-JOIN operator. Cartesian Product ISA q-JOIN where q-condition always evaluates to true. ____ SQL is based on Predicate Calculus. A query in SQL always specifies what should be included in the query result.

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
