Active databases for active repositories

摘要

The various activities necessary for constructing a softwarenproduct are described by software process models. Many of the actionsnmentioned there are supported by tools that use a repository in order toncreate, manipulate, generate, etc. the deliverables. The process isntailored for each project to necessary work and planned with respect tonexisting resources. This results in a schedule for each project that isnmanually compared with ongoing work. We introduce the idea of activenrepositories that partially automate scheduling and controlling of thenactivities described within a process model. The notion of activenrepositories is based on active database technology that allows forndetecting events and triggering the corresponding actions. Events arenstate changes in the repository or raised by external components, e.g. anclock or CASE tool. Actions manipulate the repository, trigger CASEntools, signal external systems or notify the user
