  • Layered Architecture is a kind of nodule decomposition techniques, which decomposes a program by generality This paper proposes a ]aver based method for recovering layered architecture from object-oriented program and checking conformance against architectural document. To specify the rules for layered style in object-oriented program, we define a partially ordered set on modules by module use relationship and module layer relationship by module override relationship. The meaning of module layer relationship is explained with an example from design patterns. Steps to recover layered architecture from program are described and a metamodel for the recovery is proposed. Architecture recovery is performed on source codes from open-source software project, and the implication of parts that do not conform to its architectural document is discussed. As a result of checking, it is pointed out that, although the parts are considered allowable exceptions of layered architecture, their modifications should be controlled carefully.
