Hi,

I am trying to model the following process:

1. User clicks on 4 desktop applications.

2. these applications load files into a network Drive.

3. There is a program  PRG1 running in the background (every one hour) that iterates through each file,  extracts the customer ID in each file and checks if it exists in another system, SYS1.

4. If the customer ID is existing in SYS1, then the file for that ID is uploaded into the Database of SYS1 and then deleted from the network drive

4. The files that remain on the network drive are checked by another user at regular time intervals, if a file remains, then that customer ID is created in SYS1 by the user.

5. The next time the PRG1 runs, it finds the customer ID and uploads in database and then deletes.

I am not sure how to model this. Any suggestions,advice, inputs please?
