There is still no standardization of software measures and metrics extraction tools have to be updated frequently to handle the changes. A possible solution is represented by using an intermediate abstraction layer to decouple the information extraction process from the use of the information. In this way a metrics researcher do not have to deal with language parsing production concepts such as declarations, class specifiers, and base clauses. This paper presents WebMetrics, an automated tool for software metrics collection. The tool uses, as intermediate layer, a set of intuitive relations to describe the source code structure. These relations are stored in a database in order to calculate metrics directly by performing SQL queries. To test the architecture, we applied the tool to the source code of an opensource project in order to compute CK metrics suite.

Software evolution plays a key role in the overall lifecycle of a software system. In this phase, software developers extend the capabilities and functionality of the system to meet new user requirements. However, the maintenance process could rapidly lead to phenomena of "source code deterioration". The possibility to early detect bad software evolution patterns represents a paramount opportunity to keep the application maintainable. In this paper we propose a combined visualization to identify software evolution patterns related to user requirements. Such visualization consists in showing the evolution metrics of a software system together with the implementation of its requirements. We also show some examples on how this visualization could help to identify some "common" evolution patterns.
