—Many companies develop software product lines— collections of similar products—by cloning and adapting ar-tifacts of existing product variants. Transforming such cloned product variants into a " single-copy " software product line representation is considered an important software re-engineering activity, as reflected in numerous tools and methodologies(More)
The Service-Oriented Architecture paradigm (SOA) is commonly applied for the implementation of complex, distributed business processes. The service-oriented approach promises higher flexibility, interoperability and reusability of the IT infrastructure. However, evaluating the quality attribute security of large and complex SOA configurations is not(More)
Software reuse approaches, such as software product lines, can help to achieve considerable effort and cost savings in product development for sets of software systems with a significant overlap in functionality. However, in the practice many organizations at first develop a number of similar software products without explicitly planning for strategic(More)
—Software project forking, that is copying an existing project and developing a new independent project from the copy, occurs frequently in software development. Analysing the code similarities between such software projects is useful as developers can use similarity information to merge the forked systems or migrate them towards a reuse approach. Several(More)
We developed a reverse engineering technique, named Variant Analysis, aimed for recovering and visualizing information about commonalities and differences that exist in the source code of multiple similar software systems. The delivered information is available on any level of system hierarchy, from single lines of code up to whole software systems. The(More)
