Transformation Of Xml Document Into A Relational Database
Résumé: The transformation from XML to relational database is very important technique in processing data; one common reason for transforming is that existing SQL applications might still require access to the data in relational format. For example, legacy applications, packaged business applications, or reporting software do not always understand XML and have fixed relational interfaces. Therefore you might sometimes find it useful to share all or some of the data values of an incoming XML document into rows and columns of relational tables. In our work the first step was creating classes to analyze if the XML (with DTD or simple) document is valid, the second step is checking the prolog, and the tags. After that, checking SQL errors process must started. If no errors occurred, a relational database is generated from the XML document. The developed application could just detecting errors, showing simple messages. As a future work we propose that those errors will be treated in order to help users having more ability when they use this application. Besides this we have mentioned that we have used the DTD as grammar for XML document. As a perspective , our application can be ameliorated to manipulate XML schema in the place of DTD.
