ServiciFiServiciFiConclusion

What can be reused from the initial related projects/works?o Method fragment of SO development methodso Code extraction techniques

How can we improve our techniques of extraction? o Slicer for other languages like COBOL

How can we make the extraction language platform independent? o Code query technologies

Can we use design pattern (architectural) to local the potential services in legacy codes?o Source code analysis for data and functional dependency
