ICTDBS506 Topic 3 - Intro

A database management system (DBMS) helps improve organizational security, integration, compliance, and performance. Which benefit of a DBMS ensures that data is shared quickly, effectively, and securely across an organization?

• Improved data sharing and data security

• Effective data integration

• Consistent, reliable data

• Data that complies with privacy regulations

Answer explanation

Improved data sharing and data security is a benefit of a DBMS that enables users to share data quickly, effectively, and securely across an organization, ensuring data integrity and protection

What type of database management system is structured based on related information and requires the use of SQL (Structured Query Language) to interact with the data?

• Hierarchical database

• Relational database

• Network database

• Object-oriented database

Answer explanation

Relational databases are structured based on related information and use SQL as the language to interact with the data. They are designed to store data that needs to be connected in some way, allowing for easy access to information.

The benefit of a Database Management System (DBMS) that minimizes data inconsistency between files, ensuring that different versions of the same data do not appear in different places, is:

• Faster data access

• Better data integration

• Minimized data inconsistency

• Better decision making

Answer explanation

A DBMS minimizes data inconsistency by ensuring that the same data appears consistently across the database, reducing the chances of having different versions of the same data in different places [3].

The benefit of a Database Management System (DBMS) that allows end-users to generate better quality information and make informed decisions based on well-managed data and improved data access is:

• Better data security

• Increased end-user productivity

• Faster data access

• Better decision making

Answer explanation

Improved data management and access in a DBMS lead to better data quality, which in turn allows end-users to make better decisions based on accurate and valid information.

A major advantage of using a Database Management System (DBMS) is:

• Simple data abstraction

• Reduction in data redundancy

• Better data integration

• Scalability

Answer explanation

DBMS provides features to prevent the input of duplicate data in the database, reducing data redundancy and ensuring data consistency
