XPEDIA: XML Processing for Data Integration

Free registration required

Executive Summary

Data Integration engines increasingly need to provide sophisticated processing options for XML data. In the past, it was adequate for these engines to support basic shredding and XML generation capabilities. However, with the steady growth of XML in applications and databases, integration platforms need to provide more direct operations on XML as well as improve the scalability and efficiency of these operations. In this paper, the authors describe a robust and comprehensive framework for performing Extract-Transform-Load (ETL) of XML. This includes full computational model and engine capabilities to perform these operations in an ETL flow, an approach to pushing down XML operations into a database engine capable of supporting XML processing, and methods to apply partitioning techniques to provide scalable, parallel processing for large XML documents.
