Quizplus · Accepted Answer

An entity-relationship diagram or E-R diagram is a graphical representation of the entities, associations, and data elements for an organization or business area. It shows the relationships between the different data elements and how they relate to each other. A logic model is a different kind of diagram that shows the inputs, outputs, and activities of a program or intervention. A data-flow diagram shows the flow of data through a system, and a structure chart shows the structure of a program or system. A data tree is not a commonly used term in data modeling or information systems.
