Abstract
XML is fast emerging as the dominant standard for representing data in Internet. One efficient path to store it is transforming XML data into relational database. Exiting XML-to-RDB algorithms focus only on the structure and ignore semantic constrains, in addition, their inputting is not XML-Schema but DTD. In this paper, we present an algorithm for mapping XML-Schema to relational schema. Our main ideas are as follows: 1) On the basis of regular tree grammar, propose a concise and precise formalization representing method named FD-XML for XML-Schema; 2) Extend the traditional ER model to Extended ER model (EER); 3) Map FD-XML to EER and then EER to relational schema. With the above procedures, the mapping algorithm comes into being, where both correct data structure and integrated data constrains are translated.
We differentiate two terms, XML Schema(s) and XML-Schema; the former is a general term for a schema for XML, while the latter refers to one of the XML Schemas proposed by W3C.
