Overview

Universal XML is an easy to use XML data gateway to transform your data effectively.More requests for interoperability and data exchange through the Internet make XML (Extensible Markup Language) as a dominant standard language. Though much work has been done on translating relational data into XML documents and vice versa, there is no method for massive data transmission on the Internet. Moreover, most XML-enable database management systems can only translate a few relations into XML documents without preserving data semantics, which is insufficient for information highway on the web. People are also required to prepare different query languages for operating different database models. As a result, XML databases, which fulfill the above requirements, have emerged. It stores XML documents and preserves its physical document structure, support document-level transactions and queries in XML query language. To retrieve the relational data on the web rapidly, its equivalent XML documents must be created and transmitted on the Internet. Replicate databases also let users inter-operate XML database and relational database by their own familiar query language such that users can use XQL and SQL to access replicate XML documents and relational database respectively. Snapshot facilities are applied to replicate XML documents if there is any change in the relational database.

Universal XML Data Gateway is a powerful software tool, which helps in replicating a relational database into an XML (Extensible Markup Language) database. It allows users to benefit from rapid data and format interchange on the intranets and World Wide Web. Moreover, all relevant DTD (Document Type Definition) files are generated. Each DTD file defines the structure and legal building blocks in each XML file, so it also helps in designing and validating the XML file.

Objective
