Entry Certificate in Business Analysis (ECBA) — Question 67

Which technique would the business analyst (BA) consider to show the transformation of data?

Answer options

• A. Sequence diagram
• B. Data flow diagram
• C. Data modelling
• D. Flowchart

Correct answer: B

Explanation

The correct answer is B, as a Data flow diagram specifically depicts the flow of data within a system and how it is transformed during processing. The other options, while useful in their own contexts, do not focus primarily on the transformation of data; for instance, a Sequence diagram emphasizes the order of operations and interactions, and a Flowchart represents processes but not specifically data transformation.
