Conceptual Modules

A conceptual module (CM) is a logical module that can be overlayed on an existing system. The logical module can include snippets of code from multiple parts of a system. Tool support is available to create CMs, report the interface to a CM, to report on the data and control interactions between CMs, and to report on the data and control interactions between CMs and the existing source. We have used this approach to help support reengineering tasks. The behavioural concern modelling project is extending this idea to help support reasoning about concerns that crosscut a system.
