On an XML Data Model for Data Integration
Wolfgang May, Erik Behrends
Abstract:
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.
