【摘要】 电子表单技术旨在实现企业间数据的传输与共享,代替传统的以纸质表单为中心的文件制作、传输和存储方式,构建一种基于Web的高效、准确、可靠的电子贸易系统。电子表单系统可以作为电子贸易系统的一个子系统,实现电子表单的可视化设计、自动生成与动态发布。电子表单系统在整个电子贸易中扮演着十分重要的角色,设计和实现一个完整的电子表单系统具有重要意义。 本文首先对电子表单系统进行了总体设计,将整个系统分成数据获取、表单内容设计、表单样式设计、表单生成和表单发布等五个功能模块,在分析系统用例图的基础上,设计了模块间的接口,接着对整个电子表单系统的实现技术进行了分析。 电子表单的可视化设计是指用户采用表单可视化设计工具来设计和开发表单的过程。电子表单的可视化设计工具是电子表单系统的重要组成部分,通过它可以完成表单的内容设计、样式设计和自动生成。本文设计和分析了电子表单的显示模型、工作模型和XML格式,并在此基础上设计和开发了电子表单的可视化设计工具。采用Java技术来实现可视化设计工具,保证了其运行的平台独立性。 PDF是电子表单的一种非常理想的格式,它具有在不同平台不同显示环境下却保持相同外观的优点。为了将设计好的表单生成PDF格式,本文设计并实现了一个通用的PDF软件包,用来将XML格式的电子表单按照设计好的样式生成PDF格式的表单。整个PDF软件包依据PDF规范1.3版本,采用面向对象设计方法设计,具有良好的可扩展性和易用性。 电子表单除了可以以PDF格式交换和发布外,还可以采用HTML、WML等格式。本文提出了一种电子表单的多形态发布技术,就是使用XSLT技术将XML格式的电子表单转换成HTML、WML及PDF等多种形式,按照表单消费者的不同需求发布到Web上。

【Abstract】 The goal of electronic form technology is to enable exchange of data among enterprises, replace traditional paper-based trade documents and construct an efficient, exact and reliable web-based e-trade system. Electronic form system is a subsystem of e-trade system, which implements visualization design, automatic generation and dynamic publication of electronic form. Electronic form system plays an important role in the whole e-trade system. It is significant to design and implement an electronic form system.Preliminary design of electronic form system is first introduced in the thesis, which divides the whole system into five functional modules such as data extraction, content design, appearance design, form generation and form publication. Based on the analysis of use case diagram the outer interface of each module and the implementation technology of the system are selected and analyzed.The tool for visualization design of electronic form is an important part of electronic form system, which implements form content design, style design and automatic generation. The thesis analyzes display model, working model and XML format. The advantage of JAVA as the implementation technology is platform independence of the tool.PDF is the most appropriate format of electronic form, which ensures unified form appearance on heterogeneous platforms. In order to generate electronic form in PDF format a general PDF software toolkit is developed. The toolkit is based on PDF specification 1.3 and has good expansibility and usability.Electronic form can be published not only in the format of PDF, but also in the format of HTML, WML and so on. The thesis presents multi-channel publication of electronic form, which transforms XML format into HTML, WML and PDF format through XSLT technology. This satisfies different requirements of electronic form consumers.
