It allows user-bounded, quantitative queries on projects, files, or other similar programming entities.
Queries determine the current status of an entity relative to a given quantitative measure.
Results of the queries are output to a window. In the Metrics QFS, the query produces a measure for a specific entity, at a point in time and is intended for use on an ongoing basis to monitor the progress of a project. The Programming Standards and Structure QFSs use the same measures to calculate a quality score for a given project. A QFS is a collection of weighted filters used to address a particular aspect of development. Applied to the current code base, the QFS provides quality assessment.
