Products can be purchased by inserting the correct number of coins into the machine. A user selects a product from a list of available products, adds coins, and either gets the product or gets the coins returned if insufficient money was supplied or if the product is sold out. Products can be restocked and money removed by an operator.

- 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.has a and is are mutually exclusive relationship in oop true or falseSuppose the due date for a book depends not only on the date the book issued but also on the following factors; - member type (assume 3 types of member -regular, senior, academics- and define rule for these types) - number of books already issued to the member (define a rule yourself) For the requirement defined above, answer the following questions;- Update all Use Case(s) which are affected- Update the Domain Model if necessary- Update all Sequence Diagram(s) and discuss your design in terms of Grasp Patterns Define a simple tax (%10 percent of the sale is added to the sale total) for sale processing. - Update all Use Case(s) which are affected - Update the Domain Model if necessary - Update all Sequence Diagram(s) and discuss your design in terms of Grasp Patterns
