J2EE平台上的所见即所得的HTML电子表格工具的设计

A Design Tool for Dynamic WYSWYG Form on J2EE Platform

本文介绍了一个MDA软件开发工具的设计思想和实现工具。该工具可以根据MDA中的平台无关模型的信息,由用户通过所见即所得的方式来编辑HTML表格。用户编辑了HTML表格框架后,可以基于PIM中的ER模型来定义表格中各个单元格的值。用户在编辑的过程中就可以直接看到表格的最终显示。这个工具和我们研究的其它两个工具协同使用,可以高效地把PIM转换成为J2EE平台上的应用程序。

This paper introduces the design idea and implements tool of a MDA software development tool. The usage of the tool is that users can define and edit HTML table in a ＂what you see is what you get＂ manner according to information specified in platform independent models. When the edit work of the framework of the HTML table has finished, users can define the value of every cell according to the ER models of the PIM. Users could see the final display of the HTML table during their edit process. This tool cooperates with the other two tools developed by my research group, leading to automatic and efficient transformation from platform independent model to application on J2EE platform.
