Research On Purchasing Management System Architecture Based OnWorkflow

Under the development of ISCM background, this text presents the workflow's principle and some questions about software engineering such as system development process, method, and tools. This article emphatically studies the model of architecture and component of purchasing management system software based workflow , and proposes some methods to optimize the architecture purchasing management system using design pattern,software architecture and workflow architecture.First the article introduces Component-oriented software development method, presents EC-ISCM model for software procedure, discusses the software architecture description language, C/S model and design pattern used methods, and expounds the relationship between design pattern and architecture and component;then discusses the workflow's design philosophy and architecture, raises an applying model that integrates the purchasing management with workflow model , and expounds workflow modeling method;then researches into a module of purchasing management based workflow,make the demand frame in abstraction region and set up a region model;moreover expounds the region design, set up the purchasing management software model and dynamic interaction model;then brings about the software architecture and components model.The purchasing management software development indicates that design pattern and software architecture philosophy have improve the software reusability. Because of bringing in the workflow, this system realizes the purchasing process automation and the purchaseing process reorganization, and improves the enterprise purchase efficiency.
