43. The term _______ is used to refer to a row.

a) Attribute

b) Tuple

c) Field

d) Instance

Answer:b

Explanation:Tuple is one entry of the relation with several attributes

which are fields.

44. The term attribute refers to a ___________ of a table.

a) Record

46. Which forms has a relation that possesses data about an individual
entity:

a) 2NF

b) 3NF

c) 4NF

d) 5NF

Answer:c

Explanation: A Table is in 4NF if and only if, for every one of its non-
trivial multivalued dependencies X \twoheadrightarrow Y, X is a
superkey—that is, X is either a candidate key or a superset thereof.

47. Which forms are based on the concept of functional dependency:

a) 1NF

b) 2NF

c) 3NF

d) 4NF

Answer:c

Explanation: The table is in 3NF if every non-prime attribute of R is non-

transitively dependent (i.e. directly dependent) on every superkey of R.

48. _____________ can help us detect poor E-R design.

a) Database Design Process

b) E-R Design Process

c) Relational scheme

d) Functional dependencies

Answer:d

Explanation:For eg.,Suppose an instructor entity set had attributes dept

name and dept address, and there is a functional dependency dept name
-> dept address.

49. Which of the following has each related entity set has its own schema
and there is an additional schema for the relationship set.

a) A many-to-many relationship set

b) A multivalued attribute of an entity set

c) A one-to-many relationship set

d) Both a and b

Answer:a

Explanation:If a multivalued dependency holds and is not implied by the

corresponding functional dependency, it usually arises from this source.

50. In which of the following , a separate schema is created consisting of

that attribute and the primary key of the entity set.

a) A many-to-many relationship set

b) A multivalued attribute of an entity set

c) A one-to-many relationship set

d) Both a and b

Answer:b

Explanation:If a multivalued dependency holds and is not implied by the

corresponding functional dependency, it usually arises from this source.
