Abstract:

XML is the standard format for data exchange between interenterprise applications on the Internet. To facilitate data exchange, industry groups define public document type definitions that specify the format of the XML data to be exchanged between their applications. In this paper, we propose a new method to convert the relational data into XML. During the conversion, we consider not only the structure of relational schemas, but also semantic constraints such as inclusion dependencies during the translation, which takes input as a relational schema where multiple tables are interconnected through inclusion dependencies and converts it into an XSchema. Finally, we present the experimental results using real schemas to validate the method.

Key words: relational schemas;semantic constraints;inclusion dependencies
