System and method for performing consistent workflow process execution in a workflow management system

摘要

A system for allowing consistent execution of a workflow process in a computer-enabled workflow management system is described. The workflow process includes at least one sequence of workflow actions, having at least one set of parallel workflow actions and being configured as a number of nodes interconnected by arcs. Each node defines and executes at least one of the workflow actions. The system includes a workflow process database accessible by the nodes of the workflow process to read and write data items when executing the workflow actions. The system also includes a module for maintaining execution consistency among the workflow actions when the nodes access the workflow process database to read and write the data items in carrying out the workflow actions. A computer-implemented method for consistently executing a workflow process in a workflow management system is also described.
