What does a data collection represent in BPMN?

• A. A single data value used by one activity.
• B. A collection of information such as a list of items or survey data.
• C. A data store entity.
• D. A user attribute.

Answer: (B)

In BPMN, a data collection represents a group of data items together, not just a single value. This is used when a task produces or consumes multiple pieces of information at once, such as a list of items or survey responses. Modeling a collection helps show that the process is handling multiple data elements as a unit, rather than focusing on one item in isolation.

Think of a situation like gathering all items in an order or collecting every respondent’s answer in a survey. That’s a collection—the set of many data items grouped together. This differs from a single data value, which would be just one piece of data used by one activity. It’s also distinct from a data store entity, which is about long-term persistence across process instances, and from a user attribute, which isn’t a data object used by BPMN processes.
