Transaction Support for Cooperative Work: An Overview of the TRANSCOOP Project
نویسندگان
چکیده
Cooperative work on shared information requires different kinds of computing system support to coordinate the work of multiple users, to establish mutual awareness among users, and to ensure the consistency of user results. These issues are currently tackled separately in various loosely related areas, such as workflow systems, groupware, and advanced transactional models. In the TRANSCOOP project, we have developed a transaction model and a specification language that provide a core functionality for information sharing in cooperative systems. The core functionality includes explicit work coordination facilities, which at the same time ensure the consistency of results. The TRANSCOOP transaction model and specification language have evolved from a requirements analysis of various cooperative application scenarios. The transaction model has been implemented as an extension of an existing object-oriented database management system. The suitability of both the transaction model and the specification language to describe cooperative scenarios is being evaluThis document gives an overview of the work done in the ESPRIT III BRA project TRANSCOOP (EP8012); it has been prepared for distribution at the TRANSCOOP Workshop on Extending Data Management for Cooperative Work, held in Darmstadt, on June 6, 1997. This document is based on [AKT+96]. The TRANSCOOP project has been partially funded by the Commission of the European Communities. The partners in the project are GMD (Germany), University of Twente (The Netherlands), and VTT (Finland). ated for a cooperative document authoring application.

متن کاملThe resource-constraint project scheduling problem of the project subcontractors in a cooperative environment: Highway construction case study
Large-scale projects often have several activities which are performed by subcontractors with limited multi-resources. Project scheduling with limited resources is one of the most famous problems in the research operations and optimization cases. The resource-constraint project scheduling problem (RCPSP) is a NP-hard problem in which the activities of a project must be scheduled to reduce the p...
