The Construction of a Flowchart & DFDs :)

4 Mar

There are a few very important,but basic steps involved when constructing a flowchart.

1.Identify the process involved.
2.Identify the particular stages involved in the process.
3.Identify the decisions that need to be made.
4.Construct the flowchart;always remember that flowcharts need to begin and end with a terminal.
5.A flowchart should preferably fit into one page, but if not an off-page connector needs to be used.
6.Possibly use comments at some stages during the process if necessary.
7.A flowchart needs to contain a title

There are also a few very important steps involved when constructing a DFD

1.Read and re-read the text you are given.
2.Extract important information and make assumptions.
3.Identify the entities in the text-depicted by nouns.
4.Highlight the process.
5.Identify data flows from within the text.
6.Construct a DFD using the information, labeling the entities, data flow and the main process.
