PMI Professional in Business Analysis (PMI-PBA) — Question 153

A type of requirements document that would be the most valuable to a database administrator would be:

Answer options

• A. an object diagram.
• B. an entity relationship diagram.
• C. a business process diagram.
• D. a data flow diagram.

Correct answer: B

Explanation

An entity relationship diagram (ERD) is essential for a database administrator as it visually represents the data entities and their relationships, crucial for database design. While the other diagrams such as object diagrams and data flow diagrams provide useful information, they do not specifically focus on the structure of the data like an ERD does.
