Designing And Realization Of The Custom Form Based On SCA

Data collection is essential, and its content and style are quite flexible in enterprise applications. Users always need fulfill various forms. Accordingly, if a custom form system can be accomplished, allowing to be extended and modified after demand has been changed, then, it will rescue the developers from a mass of simple logic web form customizing, as a result, the system will become more flexible.This article introduces the design process of the custom form specifically, which is used the multi-layered construction to realize it, and it uses the most popular lightweight J2EE frame presently which is helpful between the application program logic and first floor technology separation, and SCA module of SOA which can enhance this system's flexibility, usability and easy maintenance, and this point is this article's innovation.In the text, the author divides it into 4 main functional modules: loading module, analysis module, data processing module and store management module. The design includes the system's flow chart, use case diagram of each main modules' demand analysis and class diagram and time sequence diagram of the designing. Afterward, she will demonstrate the contact surface simply, which verifies the system's validity and usability, and highlights the code reusable, easy revision and maintenance, short development cycle and so on.This system supports many template designs, so that it is embryonic software of the producing custom form system. If it adds a form design which is based on visualization, it may be a quite perfect custom form system facing to the end-users.
