Architecture Reconstruction Guidelines
Architecture reconstruction is the process where the 'as-built' architecture of an implemented system is obtained from the existing legacy system. This is done through a detailed analysis of the system using tool support. The tools extract information about the system and aid in building and aggregating successive levels of abstraction. If the reconstruction is successful, the end result is an architectural representation of the system that aids in reasoning about the system. In some cases, it may not be possible to generate a useful representation due to the system. Architecture reconstruction generates an architectural representation that can be used in several ways. One of the main uses is for documenting the existing architecture. If no documentation exists or it is out of date, the recovered architectural representation can be used as a basis for redocumenting the architecture. The recovered 'as-built' architecture of the system can be used to check conformance against an 'as-designed' architecture. The architectural representation can also be used as a starting point for reengineering the system to a new desired architecture. Finally, the representation can be used to help identify components for reuse, or to help establish a software product line. In this report, we describe the process of architecture reconstruction using the Dali architecture reconstruction workbench. We outline guidelines for reconstructing the architectural representations of existing systems. The process that is undertaken to reconstruct an architecture can be supported by other tools and in fact can be done manually.
