Describing Software Architecture with UML

This paper describes our experience using UML, the Unified Modeling Language, to describe the software architecture of a system. We found that it works well for communicating the static structure of the architecture: the elements of the architecture, their relations, and the variability of a structure. These static properties are much more readily described with it than the dynamic properties. We could easily describe a particular sequence of activities, but not a general sequence. In addition, the ability to show peer-topeer communication is missing from UML.

Many Faces of Software Architecture

One reason that hardware design is more systematic than software design is that hardware designers have reached agreements about the description levels for design artifacts. We hypothesize that quality and productivity in software development would be improved if software designers were to arrive at similar agreements. As a first step, we look at representations related to software architecture.
