Dependency Models to Manage Software Architecture

Abstract:
This talk will present a Dependency Structure Matrix (DSM) based 
approach to specify and manage the architecture of large software 
systems. The system is decomposed into a hierarchy of subsystems with 
the dependencies between the subsystems presented in the form of a matrix.

This yields a number of key benefits: The adaptation of DSM is highly 
scalable compared to the directed graph approaches that are common 
today. The specification is precise and architectural violations can be 
checked automatically. Finally, there are a variety of matrix algorithms 
that can be applied to organize the matrix in a form that reflects the 
architecture and highlights patterns and problematic dependencies. The 
talk will show the actual application of this technique to a real 
open-source system to see how it can be used to discover, analyze and 
manage existing systems.
