Abstract
Legacy system software generally comprises a database and a collection of application programs in strong interaction with the former. They constitute critical assets in most enterprises, since they support business activities in all production and management domains. Legacy systems: they typically are one or more decade old, they are very large, heterogeneous and highly complex. Many of them significantly resist modifications and change due to the use of ageing technologies and to inflexible architectures. Since they nevertheless are due to evolve, sophisticated techniques have been elaborated that allow programmers and developers to identify and understand the logic of the code fragments and of the data structures that are to be changed, despite the lack of precise and up to date documentation. Recovering the required knowledge and control of poorly documented software components is the main goal of software reverse engineering.
