Workflow-Oriented Research On Electronic Custom Architecture

Based on research and development of Electronic Custom Software, this paper discusses Electronic Custom software architecture in design and realization, with guidance from the multiple methodologies of Workflow-Oriented Programming, Object-Oriented Programming together. In the process of research, organization model, process model, and resource model are analyzed, especially the process model of Electronic Custom. UML, OPN and ACME are utilized combined with Software Architecture and Design Pattern.Firstly, the methods of workflow modeling are discussed, including organization model, process model, and resource model. The object architecture of workflow meta-process definition is proposed based on the meta-model of process definition which was presented by WfMC. The process definition XPDL template of Electronic Custom is proposed.Then, the analysis and design on process model are focused. The requirement analysis of Electronic Custom is completed. Detailed description of Custom business process is proposed, and use case model and activity model are built. The process model of checking declaration is described by workflow diagram.In design phases, this paper focuses on disposal of Custom which is the key point of Electronic Custom. Design on architecture of Custom disposal is completed. UML is utilized to describe the class architecture and sequence model; ACME is utilized to describe the architecture. OPN is utilized to optimize the model combined with class model and sequence model, improving the dynamic capability of model.The analysis and design of organization model are completed. With the organization diagram of Custom, use case models of Custom organization are built. The E-R diagram of Custom organization model is presented.In the realization phases, typical implementation of Electronic Custom architecture is put forward.The software methodologies and design ideas analyzed are adopted in the research and development of Electronic Custom. They can optimize software model and resolve the issue of dynamic capability. They are proved to be effective in practice.
