Certification of Capability in Business Analysis (CCBA) — Question 419

You are the business analyst for your organization and you're creating a data flow diagram to show how information is input, processed, stored, and output from a system. Which element of a data flow diagram represents a process that transforms data by combining it with other data?

Answer options

• A. Data flow
• B. External entities
• C. Data process
• D. Concatenation

Correct answer: B

Explanation

The correct answer is B, External entities, as it represents the sources or destinations of data outside the system that interact with the processes. The other options do not specifically represent the transformation of data by combining it with other data; for instance, Data flow indicates the movement of data, Data process refers to the activities performed on data, and Concatenation is a specific method of combining data, not a process element in a data flow diagram.
