Handling Change Management using Temporal Active Repositories

. Business Re-engineering requires frequent changes in the enterprises ' information systems, however the current technology of data dictionaries is not effective for the tracing of required changes and their management. In this paper we introduce an architecture of change management using active temporal repositories. Flexible change management allows the support of information about past or future versions of information systems, as well as the capability to retrieve and update temporal information. The implementation of change management in a temporal environment is carried out by the partition of the temporal universe among temporal agents, each of them handles a single version of an application with a required collaboration among them. The change management process, and the inter and intra agent processing are described in this paper. keywords: change management, information agents, cooperative databases, temporal databases, active databases 1 Introduction and Motivation 1.1 Back..
