What diagrammatic models can be used to represent the flow of data through a system?Group of answer choicesTerminator, process, input/output, decision, subprogramProcess, external entity, data store, data flowModule, parameter, flag (control variable), decision, repetitionAll of the above
Solution
The diagrammatic models that can be used to represent the flow of data through a system include Process, External Entity, Data Store, and Data Flow. These elements are typically used in Data Flow Diagrams (DFDs), a common tool for representing the flow of data in a system.
Terminator, Process, Input/Output, Decision, and Subprogram are elements used in flowcharts, another type of diagrammatic model, but they are not typically used to represent data flow.
Module, Parameter, Flag (Control Variable), Decision, Repetition are elements that might be used in other types of diagrammatic models, such as structure charts or pseudocode, but again, they are not typically used to represent data flow.
So, the correct answer to your question would be "Process, external entity, data store, data flow".
