When to Use Physical Diagrams

When to Use Physical Diagrams

Most people draw this kind of information informally, but gradually people are formalizing the diagrams to fit in with the UML. I draw these diagrams whenever I have to show physical information that is different from the associated logical information. Most times, I find that I draw at least one diagram that shows nodes and major components in the style of Figure 10-1. I use pictorial icons if I can do so without the diagram getting too cluttered.
