> I've been asked to do a data flow chart and a process description chart
for a whole bunch of website CGIs. I can gather from their titles what these
charts basically are. What I am wondering is if there are standards for data
flow and process description charts, in terms of what symbols to use to mean
what, or what information must be represented? Can anybody point me in the
direction of a website, or any other resource, for a description of these
charts and their standards/requirements?
Hi Kandis,

Dig around these sites - <--- nice FREE white paper and FREE trial <--- they make a product tool which is very
simple to use.

Go to and enter CASE tool, you will get tons of links
for additional products which may be a little beyond what you seek.

Once you learn the concepts behind data models -- simple flow diagrams are
easily created with programs like VISIO.

Also, for you reading enjoyment should you desire to become the new Techwr-l
data flow diagram expert... dive into the bibliography I include below. Good
