A database design may be based on existing data.

Solution (By Examveda Team)

Option A: True
This option suggests that a database design may be based on existing data. This statement is accurate. When designing a database, developers often analyze existing data sources to understand data structures, relationships, and business rules that need to be captured in the database schema. Existing data can provide valuable insights into how data is currently organized and used within an organization. By basing the database design on existing data, developers can ensure that the new database effectively supports current business processes, maintains data consistency, and meets the organization's requirements for data storage and retrieval.

Option B: False
This option suggests that a database design may not be based on existing data. This statement is incorrect. Designing a database without considering existing data would overlook valuable information about data relationships, integrity constraints, and business rules that are already established within the organization. Ignoring existing data could lead to inefficiencies, inconsistencies, and challenges in integrating the new database with existing systems and applications. Therefore, basing the database design on existing data is a common and recommended practice to ensure alignment with organizational needs and data management practices.

Conclusion: The correct answer is Option A: True because designing a database based on existing data helps developers understand current data structures and requirements, ensuring that the new database effectively supports business processes and maintains data integrity. This approach facilitates smoother integration with existing systems and enhances overall data management practices within the organization.
