Understanding legacy systems with OSK

Abstract

The tool named OSK (Operational System Knowledge), is the result of cooperation between Sintesi and Software Engineering and Applications Laboratory of CNUCE Institute of C.N.R. In fact, OSK is derived from the basic ideas implemented in a SEAL prototype named TROOP developed in the framework of C.N.R. Progetto Finalizzato. OSK can be used in a variety of scenarios involving the maintenance of operational systems like: impact analysis; re-documentation, restructuring and re-engineering; migration to ERP; source code quality evaluation; support for data-warehousing activity (data extraction, metadata identification, etc.); code generation. OSK comprises a set of modules built around a software repository, holding the knowledge of the analyzed systems.
