Converting Relational to Qualified XML Schema with Referential Integrity Constraint

Abstract

Data Exchanging is one of the most important sections in Web Application. XML is flexible and platform independent which provide for data exchanging. Most of the features such as information exchanging and information extraction are depended on the XML schema. To provide these features, XML schema needs to be qualified to exchange data over the heterogeneous applications. The understanding of the human reader is the important quality factor of XML schema. This paper presents the converting method for relational database to qualified XML schema with two main processes (1) highly nested with referential integrity constraints depends on the database design and (2) grouping the common attributes in the relations which can be applied for the large database. The quality of the resulted XML schema document is described with the complexity measurements.
