Where can I find Context Diagram notations?

[sushma]

I am trying to draw context diagram and i do not find any symbol which
represents a process or a data store. also i do not see any template for
context diagrams. Please can you suggest an alternative

Look for DATFLO_M.VSS in your Visio application folder.
There Data store and Oval process would be found.

Template of context diagram is IDEF0_M.VST.
Here, _M should be totaly modified in your system is not in metric.
