CompTIA Data+ (DA0-001) — Question 231

A complex report is being created from a database. Within the database the storage location of the orders, packaging, and logistics details is unclear. The table's attributes names are abbreviated and not easily identifiable. Which of the following types of documentation would be most useful for reference lookup?

Answer options

• A. Data flow diagrams
• B. Database specifications
• C. Entity-relationship diagrams
• D. Data dictionary

Correct answer: D

Explanation

The correct answer is D, the data dictionary, as it provides detailed information about the attributes of the database, including their meanings and relationships. Options A, B, and C do not focus on attribute definitions or specifics, making them less useful for clarity in this context.
