  Abstract

XML makes it possible for data to be exchanged regardless of the data model in which it is represented or the platform on which it is stored, serving as a standard for data exchange format on the internet. Especially, it is natural to send XML data without DTD on the internet when XML is data-centric. Therefore it is needed to extract relational schema to store XML data efficiently, to optimize queries, and to publish data which have been stored in the relational database in the XML format. In this paper, we propose a method to generate relational schema from XML documents without DTD and store XML data using upper/lower bound schema extraction technique for semistructured data. In extracting a lower bound schema, we especially show an efficient technique for creating relational schema by using simulation which is more advanced than the datalog method.
