Abstract : Because a system's software architecture strongly influences its ability to support quality attributes such as modifiability, performance, and security, it is important to be able to analyze and reason about that architecture. However, architectural documentation frequently does not exist, and when it does, it is often out of sync with the implemented system. In addition, it is rare that software development begins with a clean slate; systems are almost always constrained by existing legacy code. As a consequence, we need to be able to extract information from existing system implementations and reason architecturally about this information. This paper presents Dali, an open, lightweight workbench that aids an analyst in extracting, manipulating, and interpreting architectural information. By assisting in the reconstruction of architectures from extracted information, Dali helps an analyst redocument architectures and discover the relationship between 'as-implemented' and 'as-designed' architectures.
