Figure 1 is an example to illustrate the notation. A better example is shown in Figure 2. Software elements are now simply listed by their physical filenames, information that developers are very likely to be interested in, and thus a more compact diagram is possible. I've also used a drum as a visual stereotype for the University DB database, making it easier to distinguish on the diagram. Another difference is that the concise version shows less details, not as many tagged values are shown as this information can be captured in either supporting documentation, configuration files, or source code. Deployment diagrams tend to become very large very quickly because they reflect the physical complexities of your system, therefore a concise notation becomes critical to your success.
