A general user-defined negotiation application-based AuTrA system for computer supported collaboration work

Web services have capabilities that make them suitable to meet the requirements posed by collaborative editing applications (CEAs). In this paper we describe how AuTrA(Adaptable user defined Transaction relaxing Approach), a system for composing web applications that allows user-specified varying of transaction characteristics, can be usefully applied to collaborative editing. We show how the application of AuTrA can be efficacious for business processing by increasing work throughput. A major feature of AuTrA is support for relaxation of any ACID property of transactions in certain circumstances.
