Computer Science originator contributor text Technical reports New York Department of Computer Science, Columbia University 1996 Decentralized workflow management systems (WFMSs) provide an architecture for multiple, heterogeneous WFMSs to interoperate. Atomicity is a standard correctness model for guaranteeing that a set of operations occurs as an atomic unit, or none of them occur at all. Within a single WFMS, atomicity is the concern of its transaction manager. In a decentralized environment, however, the autonomous transaction managers must find ways to cooperate if an atomic unit is split between multiple WFMSs. This paper describes a flexible atomicity model that enables workflow administrators to specify the scope of multi-site atomicity based upon the desired semantics of multi-site tasks in the decentralized WFMS.
