What is described by means DFDs as studied earlier and represented in algebraic form?
| Data flow | |
| Data storage | |
| Data structures | |
| Data elements |
Question 9 Explanation:
● A data flow diagram (DFD) is a way of representing a flow of a data of a process or a system (usually an information system)
● The DFD also provides information about the outputs and inputs of each entity and the process itself.
● A data flow diagram has no control flow, there are no decision rules and no loops. Specific operations based on the data can be represented by a flowchart.
● The DFD also provides information about the outputs and inputs of each entity and the process itself.
● A data flow diagram has no control flow, there are no decision rules and no loops. Specific operations based on the data can be represented by a flowchart.
