Data exchange for document-centric XML
Evgeny Sherkhonov · 2014
Data exchange has been one of the most popular topics in the database community for the past several years. Data exchange is essential for transferring, unifying and querying heterogeneous data -- tasks which very often arise in practice. Although the field is quite well-established and the theoretical foundations are clear for relational and XML data exchange, there are still some open problems motivated by both theory and practice. In this proposal we show one example of a data exchange problem which is not captured by the conventional data exchange setting for XML. In this example the central objective in the process of data exchange is to preserve the document order. This kind of data exchange setting we call document-centric data exchange. With introducing a new formalism to capture such a data exchange scenario, new solutions for common data exchange related problems are needed.
