Learning About the System and Its Applications
You should also develop a diagram of each major application running on the system.
Each application diagram should reflect these system elements:
•
Requesters
•
Servers
•
Data files, including how the file is structured and accessed, where the file is
located, whether it can be moved, and whether it can be partitioned
•
Paths between requesters, servers, and files. Include the approximate number of
messages over each path.
Figure 7-4 on page 7-8 shows a sample application diagram.
