NPTEL Introduction to Database Systems Week 3 Assignment Answers 2024

1. Some relations may not have a key.

2. An attribute name should not be used in more than one relation.

3. A key of a relation may have more than one attribute.

4. The elements of the domain of an attribute may be ordered pairs of values.

5. Some relations may not have a foreign key.

6. A foreign key in a relation should consist of exactly one attribute.

7. A foreign key in a relation R can NOT be used to refer to tuples in R itself.

8. If A is a foreign key in R, no null values are permitted in the column A in any instance of R.

9. Suppose A is a foreign key in R that refers to tuples of S using values of the key attribute B of S. Let X be the set of all non-null values of column A and let Y be the set of all values of column B. Identify the correct relationship between X and Y that holds in all instances of R and S:

• X is a subset of Y
• X is a proper subset of Y
• Y is a subset of X
• X need not be a subset of Y and Y need not be a subset of X

10. Consider the following relations S1(P,Q,R) and S2(T,U,V) and the given instances. What is the result of the relational algebra expression

• Empty relation
• { (2,4), (3,6) }
• A relation with scheme (P,Q) and tuples { (1,2) }
• A relation with scheme (P,Q) and tuples { (1,2), (2,4), (3,6) }

Using the relation instances given in the Question 10, find out how many tuples will be there in the result of the following relational algebra expression:

12. Consider the four relations R1(A, B, C), R2(X, Y, Z), R3(A, B, D) and R4(U, X, Y). The domains of the attributes are: A – integers; B – strings; C – single characters; D – { ‘M’, ‘F’ }; U – integers; X – strings; Y – single characters; Z – { ‘M’, ‘F’ }. Identify the pair of union-compatible relations:

• Pair R1, R3
• Pair R1, R4
• Pair R2, R3
• Pair R3, R4

13. The ​ join ​ relational algebra operator can NOT be expressed using other operators.

14. The ​ cross product ​ relational algebra operator requires its operands to be union-compatible.

15. The ​ difference ​ relational algebra operator requires its operands to be union-compatible.

16. When ​ project ​ is applied on an instance ​ r , ​ the size of the result will always be the same as that of ​ r.

17. Consider the following relations S1(P,Q,R) and S2(P,R) and the given instances. What is the result of the relational algebra expression?

• A relation with scheme (Q) and tuples { (2), (4) }
• A relation with scheme (Q) and tuples { (2), (4), (6) }

18. Consider the following relation S1 and its given instance. What is the size of the result of the following relational algebra expression on the relation S1?

19. On the same relation given in Question 18, what is the size of the result of the following relational algebra expression?

Domain Certification

Domain Certification helps learners to gain expertise in a specific Area/Domain. This can be helpful for learners who wish to work in a particular area as part of their job or research or for those appearing for some competitive exam or becoming job ready or specialising in an area of study.  

Every domain will comprise Core courses and Elective courses. Once a learner completes the requisite courses per the mentioned criteria, you will receive a Domain Certificate showcasing your scores and the domain of expertise. Kindly refer to the following link for the list of courses available under each domain: https://nptel.ac.in/noc/Domain/discipline.html
