Dynamic Workflow Restructuring Framework for Long-Running Business Processess
نویسنده
چکیده
This chapter presents a framework for dynamic restructuring of longrunning business processes. The framework is composed of the ActivityFlow specification language, a set of workflow restructuring operators, and a dynamic workflow management engine. The ActivityFlow specification language enables the flexible specification, composition, and coordination of workflow activities. There are three unique features of our framework design. First, it supports a collection of specification mechanisms, allowing workflow designers to use a uniform workflow specification interface to describe different types of workflows involved in their organizational processes. A main objective of this characteristic is to help increase the flexibility of workflow processes in accommodating changes. The ActivityFlow language also provides a set of activity modeling facilities, enabling workflow designers to describe the flow of work declaratively and incrementally, and allowing to reason about correctness and security of IDEA GROUP PUBLISHING This chapter appears in the book, Advanced Topics in Database Research, vol. 4 edited by Keng Siau © 2005, Idea Group Inc. 701 E.
