True or False below: 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.
Consider the following ER diagram: storcid address description value Displays Store Memorabilia The above diagram represents information pertaining to stores and the memorabilia that is displayed within the stores. a) Write the SQL statements to create the necessary tables to represent the above diagram, representing as many constraints as possible. Note: you do not need to worry about specifying types for the fields, but you do need to provide suitable foreign key option(s).
