 | The scope of engineering processes tends to strengthen the argument for requiring a single source approach throughout the entire process. SGML/XML can be used as an integration platform by providing a unique data exchange and archive format. This presentation shows a multiple layer architecture for document and data management and the essential role of SGML/XML. It will also explain possible strategies for implementing the data model in SGML/XML. It covers topics such as natural addressing of objects, subclassing, and conceptual versus logical versus physical data schemes. It also includes a discussion of desired enhancements of the standards for better support of data modeling.
