Sample Questions Q1) What are "referential integrity constraints"? Give an example.

Answer: A referential integrity constraint is a rule that restricts certain actions on the database data.A referential integrity constraint is used to ensure that the values in a field in one table have matching tables in a corresponding field in another table.These constraints are enforced by the DBMS,which will not allow changes to the values of the database that would result in violations of this rule.For example,a database has an EMPLOYEE table and a VEHICLE table that are used to store data on employees and the vehicles that they are assigned to drive.The EMPLOYEE table has a column called EmployeeID that is used to distinguish one employee record from another.The VEHICLE table also has an EmployeeID column that is used to associate a vehicle with the appropriate employee.A referential integrity constraint could be used to prevent a vehicle from being assigned to an employee with an EmployeeID that does not appear in the EMPLOYEE table by requiring that all values in EmployeeID in the VEHICLE table have a matching value in EmployeeID in the EMPLOYEE table.

Sample Questions Q1) Distinguish between the primary key and a candidate key.

Answer: Both the primary key and a candidate key can uniquely identify the rows in a table.The primary key is the candidate key that is chosen by the database designer,working

with

the

users,to

uniquely

identify

rows

and

to

represent

relationships.Although any candidate key could,by definition,be selected to act as the primary key,the choice of primary key is often based on design decisions such as the amount of foreign key data that would be generated.

Q2) In general,each relation should have ________.

A)one and only one theme B)one or more themes C)exactly two themes D)one or two themes E)exactly three themes Answer: A Q3) All relations are tables,but not all tables are relations.
