| Summary: | 碩士 === 國立政治大學 === 資訊管理研究所 === 91 === The (eXtensible Markup Language) XML is fast becoming the standard data exchange across the Internet. It is suitable to describe complex-structured data. It also provides a validation mechanism to validate vocabulary used in the XML document. In order to exchange XML document, XML vocabulary needs to be defined. As a result spread out the issues of XML schema design from here. In the research, UML data model and XML schema transformation issue have been studied to develop a bi-directional mapping and transformation model. We design the bidirectional mapping and transformation model in two parts. One is from UML data model to XML schema; another is from XML Schema to UML data model. Each part has two explored subject, including XML DTD (Data Type Definition) and W3C XML Schema. We develop a sequence of transformation rules from the viewpoints of syntactic and semantic transformation. These are also two parts in the transformation model of mapping from XML schema to UML data model. We develop transformation rules from the viewpoints of generic XML constructs step by step. We build up the transformation model to make transformation method more generic, genuine, systematic, explicit, simple and easy to use. Besides, we implement a transformation editor to validate the bi-directional transformation model.
