Research And Practice Of Web Application Framework Based On Workflow

Workflow Technology is a useful way to implement Business Process Re-engineering (BPR), while domain engineering extends software engineering, and the design of domain framework is the most important thing of domain engineering. The combination of above two cannot support BPR but also can help achieve software reuse. This paper put up with a framework for the domain of the J2EE web Application implementing work flows and critical businesses, then describe and analysis it in terms of architecture, supporting services and key technologies.Chapter 1 the background and status of web framework and workflow is firstly introduced. Then followed by a brief introduction to the dissertation's architecture.Chapter 2 Introduction to the technology of workflow is presented first it is described in detail from the aspects of conception, reference model and the current status and development, and then a workflow management system which is based on the Relational Database and developed for the Web Application is analyzed through the presentations of flow definition, engineer, tasks assigning and WAPI.Chapter 3 Systematically discuss the technology of framework and web framework, some prevalent examples of web framework are also given.Chapter 4 put forward a Web Application Framework based on Workflow which is based on the research of the web applications for critical businesses, and then analyze it from its architecture, use cases, sequence diagrams.Chapter 5 introduce the Conception of Web Component for Workflow, and then discuss it from the views of business logic implementation, data exchanging between Web Components, web components management and Web Component setting, etc. Finally two examples of the web component are analyzed.Chapter 6 provide an example called Disaster Ministration Rapid Reaction System, which is based on the web application framework based on workflow, it canimplement the business process building dynamically and reengineering. .Chapter 7 summarizes the research work in this dissertation, and gives the future worked of this research.
