Efficient Storage and Retrieval of XML Documents Using XQuery

Abstract

In the last decade of the 20th century, because of the popularity of Internet, the trend is towards e-solutions for businesses. Not only apply on the electronic commerce but also on the information exchange to decrease time from material in the manufacturer to products brought by customers. However, the problem we confront today is that there are full of e-documents in businesses. XML has already been the standard of data interchange on the Internet. In the future, a large amount of data will be represented in XML format. However, most of the critical data in businesses are still stored in relational database management systems. It is difficult to query XML databases because of its textual format. In this paper we proposed a system to manage XML documents that could be queried by the query language XQuery. XML documents are stored in relational format and the XQuery expressions are translated into appropriate SQL queries. The results of the SQL queries are transformed into XML documents.
