In class we have discussed four types of Integrity Constraints: Domain Constraint, Key Constraint, Entity Integrity Constraint and Referential Integrity Constraint. Suppose that each of the following data change operations is applied directly to our COMPANY database, whose schema and instance are shown in Figures and 2 respectively. Identify all the integrity constraints (if any) that will be violated if we perform the following operations. If a constraint is violated (a) explain briefly why this happens, and (b) suggest all possible actions to be taken for correcting the cause of the violation of the constraint. a nd isianeare (1) Insert into EMPLOYEE (2)Insert into PROJECT. (3) Delete the PROJECT tuple(s) with PNA ME = Computerization' (4) Delete the WORKS ON tuples with PNO-8. (5) Update the SSN and the SALARY of the EMPLOYEE tuple(s) with DNO = 1 to 333445555' and 55000 respectively (6) Update the SSN and the SUPERSSN of the EMPLOYEE tuple(s) with LNAME Jabbar to '112233445' and NULL respectively.
