Description
Summary:Legacy systems age over time as a consequence of uncontrolled maintenance, thus they must be evolved while its valuable embedded knowledge is preserved. Software modernization, and particularly Architecture-Driven Modernization, has become the best solution in the legacy systems’ evolution. ADM defines the Knowledge Discovery Metamodel specification, now being adopted as ISO/IEC 19506 by the International Standards Organization. The KDM metamodel allows to represent all the software artifacts recovered during reverse engineering techniques at different abstraction levels. This paper presents how to use KDM to modernize legacy systems, making them more agile, preserving the embedded business knowledge and reducing maintenance costs. ► Architecture-Driven Modernization facilitates the evolution of legacy systems. ► Knowledge Discovery Metamodel allows to represent all the legacy software artifacts. ► KDM is the common interchange format to share models during software modernization.
