E) logic diagram.

Question

Quizplus · Accepted Answer

A level-0 diagram shows the major processes, data flows, and data stores of a system at a high level of detail. It is the first level of decomposition of a data-flow diagram, showing the overall view of the system. A context diagram shows the system boundaries and interactions with external entities at a high level and is less detailed than a level-0 diagram. A level-1 diagram shows the major processes of a system in more detail than a level-0 diagram. Level-00 and logic diagrams are not typically used in data-flow modeling.
