Question :

Accountants will use data flow diagrams (DFDs) to depict the physical flows of data through an AIS (like document flowcharts), or the logical flow of data through an AIS (like system flowcharts). Like document or system flowcharts, their basic objective is to document data flows in an orderly, easily, and graphic -understood format. But DFDs use fewer symbols than either document or system flowcharts, and do not need columns (like document flowcharts).

Show how a document flowchart assists each of the subsequent individuals:

A systems analyst.

A systems designer.

A computer programmer.

An auditor.

A data security expert.

Flowcharting is both an art and a science. Procedure can be used to make better flowcharts. What are these guidelines for system, document, and data flow diagram flowcharts?

Describe the four symbols used in data flow diagrams? What does each mean?

Explain why data flow diagrams are developed in a hierarchy? What are the names of some levels in the hierarchy?
