CPSC 5340 Database Design Homework 3 Rikky Patel 9-27-2015 Part: 1 3.11. Suppose that each of the following Update operations is applied directly to the database state shown in Figure 3.6. Discuss all integrity constraints violated by each operation, if any, and the different ways of enforcing these constraints. e. Insert into DEPENDENT. Answer: This operation is accepted and it can be successfully inserted. g. Delete the EMPLOYEE tuple with Ssn = ‘987654321’. Answer: This operation can’t be used. Because Ssn has been used as a foreign key of WORKS_ON, EMPLOYEE and DEPARTMENT relations ad deleting records with Ssn = ‘987654321’ will leave no corresponding entry for record in WORKS_ON relation. If we want to delete this data than we need to delete it from all the tables. h. Delete the PROJECT tuple with Pname = ‘ProductX’. Answer: This operation can’t be used. Because Pnumber has been used as a foreign key of WORKS_ON relation and deleting record with Pname = ‘ProductX’ will also delete product with Pnumber = ‘1’. Since this value has been used in WORKS_ON table so deleting this record will violate referring integrity constraint. If we want to delete this data than we also have to delete data from corresponding tables. i. Modify the Mgr_ssn and Mgr_start_date of the DEPARTMENT tuple with Dnumber = 5 to ‘123456789’ and ‘2007-10-01’, respectively. Answer: This operation can be acceptable. 3.12.
