Abstract: Systems, computer program products, and methods for extracting, evaluating, and updating the architecture of a software system are provided. In an embodiment, the method operates by defining the planned architecture for the system and extracting the implemented software code architecture from the source code of the system. The method compares the actual architecture to the planned architecture defined to identify architectural deviations, and suggested changes to the architecture are identified based upon the architectural deviations. The modeled code architecture and defined planned architecture information enables verification and determination of whether a software system's source code conforms to the intended structure of the system. The code architecture and planned architecture comparison also enables analysis and display of the effects that changes to source code may have on the structure of a software system.
