Database Fundamentals — Question 158

Which of the following is a building working model of a database system?

Answer options

• A. Prototyping
• B. Bottom-up approach
• C. Conceptual database design
• D. Top-down approach

Correct answer: A

Explanation

Prototyping is a method used to create a working model of a database system, allowing for iterative testing and refinement. The bottom-up and top-down approaches are strategies for database design but do not specifically focus on creating a working model, and conceptual database design is about structuring the database's overall framework rather than building a working version.
