In the context of balancing data flow diagrams and ERDs, what do data flows represent in an ERD?

In an Entity-Relationship Diagram (ERD), data flows are not explicitly represented as entities. Instead, ERDs use symbols to depict entities, attributes, and relationships. Entities are typically represented by rectangles, attributes by ovals or ellipses, and relationships by diamonds or lines connecting entities.

In the context of this question, the focus is on identifying what data flows would represent in relation to an ERD. Data flows in an ERD do not directly correspond to entities but instead illustrate how data moves between these entities through relationships. The correct interpretation of the relationship between data flows and their representation in an ERD would consider data flows as the interactions or links between entities rather than the entities themselves.

Understanding that data flows signify how information is exchanged can help clarify their role in modeling systems. While entities represent key objects within a system, it is the relationships that explain how these objects interact or are associated with one another. Consequently, the better understanding of these specific components within an ERD strengthens overall data modeling proficiency.
