Abstract: The current DMS-Document Management System of the Region Council provides basic indexing and document retrieval services. Unfortunately, it does not provide any form of control over the flow of documents among users. Support of coordination of work is thus very weak. In order to solve this basic problem in the Regional Council office, we proposed and implemented a Workflow Management System. The system is designed based on the generic workflow product structure suggested by the Workflow Management Coalition. It consists of a graphical Workflow Builder, a Workflow Engine that can work in both centralized and distributed environment with control data stored in the RDBMS, and a Workflow Deployment interface bundled with application wrapper servers. The Workflow Builder allows users to define a workflow by means of Trigger Modeling. The Workflow Engine drives activities through defined stages of a workflow. The Workflow Deployment user interface manages the interaction between users and the workflow engine by allowing users to instantiate new instances of workflow and presenting to the users with the outstanding activities awaiting to be performed. The design and implementation of the graphical interface of the builder, its internals as well as the components of the workflow engine are object-oriented. The wrapper servers are implemented as Active X servers conforming to COM-Component Object Model of the software giant Microsoft Corporation. It shows one viable solution to a uniform, distributed application invocation interface between custom-made or commercial applications and the workflow engine.
