Software architecture reconstruction is an interpretive, interactive, and iterative process including many activities. (1) involves analyzing a system's existing design and implementation artifacts to construct a model of it. The result is used in the following activities to construct a view of the system. The database construction activity converts the (2) contained in the view into a standard format for storage in a database. The (3) activity involves defining and manipulating the information stored in database to reconcile, augment, and establish connections between the elements. Reconstruction consists of two primary activities: (4) and (5). The former provides a mechanism for the user to manipulate architectural elements, and the latter provides facilities for architecture reconstruction.
