Certification of Capability in Business Analysis (CCBA) — Question 230

System designers are working with a business analyst (BA) during the initial stages of a project to implement a new transaction-based system. The system designers would like to have a visual that illustrates the type of information that will be input in the system, the processes it will support, and the location where it will be stored. What type of diagram meets the designers' needs?

Answer options

• A. Data Flow
• B. Use Case
• C. Activity Flow
• D. State Modelling

Correct answer: A

Explanation

The correct answer is A, Data Flow, as it effectively illustrates how information moves within the system, the processes involved, and where data is stored. Use Case diagrams focus more on user interactions with the system rather than data flow. Activity Flow diagrams depict workflow processes but do not specifically address data storage or input types. State Modelling diagrams represent the various states of an object but do not convey the movement of data.
