Opusdei-integrated environment for software development and maintenance

This paper discusses an integrated software development and maintenance environment, Opusdei, built and used for the past seven years at Hitachi Software Engineering (HSK) for its various projects. Industrial software is usually large, has many versions, undergoes frequent changes, and is developed concurrently by multiple programmers. Opusdei was developed by HSK to handle the various problems that arise in such an industrial environment. In Opusdei, all information needed for development is stored using an uniform representation in a central repository, and the various documentation and views of the software artifacts can be generated automatically using the tool repository. The innovative capabilities of this tool are: (1) Uniform software artifacts representation; (2) Inter-relation and traceability maintenance among software artifacts; (3) Tools repository and integration using tool composition scenarios; (4) Automatic documentation and versioning control. Opusdei was used in various software engineering projects and was found to improve productivity to a great extent
