| Summary: | 碩士 === 國立東華大學 === 資訊工程學系 === 90 === Most companies have their own proprietary information system that operate on their own with limited degree of information exchange using EDI standard. The current status of the cross enterprise EC can only be described as rudimentary. The level of integration and automation is of course quite low. On the other hand, XML has invaded almost all areas that are related to the internet, ever since its debut. Especially in the information integration and electronic commerce world, XML is attracting people’s attention that no other languages can. It is becoming the next standard language of the internet beyond HTML. It is also quickly becoming the standard for information exchange. The goal of this thesis is to develop XML-based technology for cross enterprise automatic information exchange and workflow management over the internet. We designed a visual tool named activity control diagram for business modeling. An activity control diagram is composed of activity notations, workflow control notations and workflow patterns. For automating the cross enterprise business process, we designed an algorithm to translate an activity control diagram into an XML workflow specification as well as the workflow engine for its execution. Preliminary implementation and evaluation results demonstrate that our tool and system can significantly simplify cross enterprise business modeling and workflow management.
