Software architecture recovery is a research field and methodological approach concerned with the process of analyzing a software system's existing artifacts (such as source code, documentation, and execution traces) to identify, extract, and represent its high-level structure, constituent elements, their relationships, and governing constraints. This inverse engineering activity investigates the latent design of systems, particularly those that are legacy or poorly documented, enabling their comprehension, analysis, maintenance, evolution, and re-engineering by providing a concrete architectural model.
