Question #1
Which of the following is the PRIMARY purpose of a Database Management
System (DBMS)?
A. To store files in a hierarchical folder structure
B. To provide an interface for users to interact with the operating system
C. To manage, store, retrieve, and secure data efficiently while ensuring
data integrity
D. To compile source code into executable programs

Correct Answer: C
Rationale: A DBMS serves as an intermediary between users/applications and
the physical data, managing storage, retrieval, security, and integrity. It does
not manage OS files (A), act as an OS shell (B), or compile code (D).




Question #2
In a relational database, a "tuple" is equivalent to which of the following?

,A. A column
B. A row (record)
C. A table
D. A primary key

Correct Answer: B
Rationale: In relational theory, a tuple is a single row in a table, representing
a single record. A column (A) is an attribute, a table (C) is a relation, and a
primary key (D) is a unique identifier.




Question #3
Which of the following SQL clauses is used to filter rows based on a
specified condition?
A. GROUP BY
B. ORDER BY
C. WHERE
D. HAVING

Correct Answer: C
Rationale: The WHERE clause filters rows before grouping or aggregation. GROUP
BY (A) groups rows, ORDER BY (B) sorts, and HAVING (D) filters after aggregation.




Question #4
A database designer wants to ensure that no two rows in a table have the
same combination of values in the StudentID and CourseID columns. What
should be created?
A. A foreign key constraint
B. A composite primary key
C. A check constraint
D. A unique index on StudentID only

,Correct Answer: B
Rationale: A composite primary key (or unique constraint across both
columns) ensures uniqueness of the combination. A foreign key (A) references
another table. A check (C) validates conditions. A unique index on
just StudentID (D) would not ensure the combination's uniqueness.




Question #5
Which of the following is a valid SQL INSERT statement?
A. INSERT INTO Students (Name, Age) VALUES ('John', 22)
B. INSERT INTO Students VALUES ('John', 22) WHERE Name = 'John'
C. INSERT INTO Students SELECT Name, Age FROM OldStudents
D. Both A and C are valid

Correct Answer: D
Rationale: A is a standard INSERT with explicit columns. C is an INSERT INTO ...
SELECT which inserts data from another table. B is invalid because WHERE is not
used with INSERT in standard SQL.




Question #6
When designing a database, a "foreign key" is used to:
A. Uniquely identify a row within its own table
B. Enforce referential integrity by linking a column to a primary key in
another table
C. Speed up query performance
D. Automatically generate sequential numbers

Correct Answer: B
Rationale: A foreign key creates a relationship between tables and ensures
that a value exists in the referenced primary key column (referential

, integrity). A primary key (A) uniquely identifies rows. Indexes (C) speed up
queries. Auto-increment (D) is a sequence.




Question #7
A table is in 1st Normal Form (1NF). Which of the following conditions must
be true?
A. All non-key attributes are fully functionally dependent on the primary
key
B. The table has no transitive dependencies
C. All columns contain atomic (indivisible) values and there are no repeating
groups
D. The table has a composite primary key

Correct Answer: C
Rationale: 1NF requires atomic values and no repeating groups. A is 2NF, B is
3NF, D is not a requirement for 1NF (though 2NF requires full dependency on
the entire primary key, which matters if composite).




Question #8
Which of the following is an example of a DDL (Data Definition Language)
command?
A. INSERT
B. CREATE TABLE
C. SELECT
D. UPDATE

Correct Answer: B
Rationale: DDL commands define or modify the database structure
(e.g., CREATE, ALTER, DROP). INSERT (A) and UPDATE (D) are DML (Data
Manipulation Language). SELECT (C) is DQL (Data Query Language).
