摘要:To describe or define the content of an XML file there is two main ways: either use a DTD or an XML Schema also called an XSD file. This last is the most recommended, however it lacks the object-oriented aspect. And also all the XML data flowing in the web are badly managed. So our paper came to resolve this problem by converting automatically XML Schemas to an Object-Relational Databases (ORDBs), which will allow us to manage XML data easily through SQL query. To do that we�re going to use the CDM (canonical data modeling) by giving an algorithm that�s going to conserve all type of relationships such as association, composition, aggregation and inheritance�, our prototype algorithm will be able to extract the schema metadata from the XML file and convert them into information represented as classes and relationships that are mentioned before. Simplicity and efficiency, those are the strength of our approach to come up with a system that generates a set of User-Defined-Types (UDTs) and a set of typed tables.
