On an XML Data Model for Data Integration

Wolfgang May, Erik Behrends


We consider the problem of integrating XML data using a warehouse strategy. In particular, we show that the DOM model and the XML Query Data Model are not suitable for data integration. We present a solution by a node-labeled graph-based data model, called XTreeGraph, for an internal XML database that represents multiple, overlapping XML trees, or tree views. The practicability of the approach is shown by a rule-based XML querying and manipulation language, implemented in the LoPiX system.
