Software Comprehension through Concern-based Queries

A concern-based approach to support software comprehension and analysis is proposed. Concerns represent various aspects of a system, like features, architectural solutions, units of work, etc., which are interesting for some stakeholders. Using concern-based queries on the software artefacts, new derived information on the system can be exposed. The results of the queries are also represented as concerns and added to the concern repository. The approach thus supports the analyzer in gradually building up an understanding on the subject system to be analyzed.
