I have not come across a standard set of shapes for laying out work flow as
it relates to databases. Normally what I have seen are shapes that
represents the transitions and comments on the line representing the
actions. Just sit down and decide what actions you need to represent and
come up with a set of shapes your organization can agree on. You will then
have a cheat sheet to help understand the drawings. Over time, you can
refine the shapes, but for now, just keep it simple.
After collecting Visio shapes for eighteen years, I am reasonably
comfortable saying that there is no widely held standard for this type of
application. (Though there should be)
With Visio, it is not a trivial task, but it is possible to write code to
read things like JCL or SQL to create Visio drawings so the process can be
automated.
Once you get into Visio, there are more experts hanging out in the
microsoft.public.visio.* newsgroups.
