Question 1

What is the primary function of a Database Management System (DBMS)?

Accepted Answer

To manage and control databases efficiently

Answer

The primary function of a Database Management System (DBMS) is to efficiently manage, store, retrieve, and organize data in a structured manner. It provides an interface for users and applications to interact with the database, ensuring data integrity, security, and concurrent access. A DBMS is fundamental for handling large volumes of information reliably.

Question 2

Which language is primarily used for managing data in a relational database?

Accepted Answer

SQL

Answer

SQL (Structured Query Language) is the standard language specifically designed for managing and manipulating data in relational databases. It allows users to perform various operations such as querying data, inserting new records, updating existing ones, and defining database schemas. Its declarative nature makes it highly effective for interacting with relational database management systems.

Question 3

What is normalization in databases?

Accepted Answer

Organizing data to minimize redundancy

Answer

Normalization in databases is the process of organizing data to minimize redundancy and improve data integrity. It involves structuring tables and columns according to a series of normal forms, which helps eliminate duplicate data and reduce anomalies during data insertion, update, or deletion. This optimization ensures data consistency and efficient storage.

Question 4

Which of the following is a characteristic of relational databases?

Accepted Answer

Data is stored in table structures with defined relationships

Answer

A characteristic of relational databases is that data is stored in a structured format using tables, also known as relations. Each table consists of rows and columns, and relationships between different tables are established through common fields, typically using primary and foreign keys. This tabular structure allows for efficient data organization, querying, and integrity management.

Question 5

What is the role of an information system in an organization?

Accepted Answer

Support business processes and decision making

Answer

The role of an information system (IS) in an organization is to collect, process, store, and distribute information to support business operations and facilitate decision-making. IS helps streamline processes, enhance communication, and provide valuable insights for strategic planning and problem-solving. By leveraging data, information systems enable organizations to operate more efficiently and effectively.
