The Cactis project: database support for software environments

The Cactis project is an on-going effort oriented toward extending database support from traditional business-oriented applications to software environments. The main goals of the project are to construct an appropriate model, and develop new techniques to support the unusual data management needs of software environments, including program compilations, software configurations, load modules, project schedules, software versions, nested and long transactions, and program transformations. The ability to manage derived information is common to many of these data needs, and the Cactis database management system has the ability to represent and maintain derived data in a time- and space-efficient fashion. A central contribution of Cactis is its integration of the type constructors of semantic models and the localized behavior capabilities of object-oriented database management systems
