DFD-how to describe a process that doesn;t always connect to db? 
Modified By UtaChan  on 8/23/2012 6:57:45 AM)

How do I describe a main process which gets informatio from another process ans stores it for future uses.
Then when it's called each time for a different reason it uses the stored information rather than calling the db connection again.

Can I simply break it to small processes each triggering a db conneciton though it doesn;t actually do that?

use a process flow instead 

 data flow diagrams show all possible links with no time dependency. To show what you want to show use a flowchart/process flow/system flow instead.

 

It might look something like

start process

first time?

   Yes - get info from database

           save data for further use

   No - use saved data

continue processing
