Distinguish between entity relationship diagrams, data flow diagrams, and system flowcharts.

Solutions

Expert Solution

Entity relationship diagrams represent the relationship between entities (resources, events, and agents) in a system. Dataflow diagrams represent the logical elements (i.e. what is being done) of a system by illustrating processes, data sources, data flows, and entities. System flowcharts represent the physical elements being used (i.e., how the tasks are being conducted) by illustrating the relationship between input sources, program, and output products. System flowcharts can also represent both the logical and physical elements of manual systems and also illustrate the preparation and handling of documents.
