Reconfigurable Web-based Application Design And Realization

As the development of IT, Internet becomes one of the most important media for information spreading and storage. Web-based transaction processing systems are widely used, such as the bank transaction system, on-line ordering system or enterprise resource processing.Businesses today are facing many pressures------pressure to compete in afast-paced ever-changing climate, pressure to constantly reduce costs to remain competitive. Becoming "on demand" means preparing your organization for success in this difficult climate. There are several dimensions to becoming an on demand business, and reconstructable business processing system meets the most of this requirements.This paper first introduces some the popular technologies for reconstructing, analyzing the advantages and disadvantages of less attention to high granularity business logic. When business logic must change, often high granularity business logic need changing too, because one small change may cause many other changes in different places. So, this paper studies the subject of how to reconstruct high granularity business logic, and proposes a new kind of business logic describing language, which consists of form flow, event flow and data flow; then the paper designs and implements the reconstructable system based on MVC pattern, and at last it proves the usability through performance tests. The main points in this paper are listed below:1 A event-driven business describing language was designed to develop Web application, implementing the reconstructability of form flow, event flow and data flow and easily handling high granularity business logic.2 A MVC-based reconstructable system was designed, comprising main controller, event dispatcher, form navigator, business script engine, database accessing module and etc.3 The reconstructable Web application is implemented, with supports for Ajax new technique.As an enterprise Web platform, the reconstructable system breaks the traditional Web model, supports high granularity business logic reconstruction, and has the...
