Answer to Question 2

The guidelines for constructing DFDs are completeness, consistency, timing considerations, the iterative nature of drawing DFDs, and drawing primitive DFDs. Completeness refers to the extent to which all necessary components of a data-flow diagram have been included and fully described. Consistency refers to the extent to which information contained on one level of a set of nested data-flow diagrams is also included on other levels. Timing is not indicated on DFDs. Iterative development recognizes that requirements determination and requirements structuring are interacting analysis sub-phases. Primitive DFDs are the lowest level of decomposition for a data-flow diagram. The analyst must make a determination of when she has reached the primitive level DFDs.
