Representing Changes in XML Documents Using Dimensionschange operations on XML documents can be represented in MXML, and show that temporal XML snapshots can be obtained from MXML representations of XML histories. We also argue that our model is capable to represent changes not only in an XML document but to the corresponding XML Schema document as wel

Updating XQuery Views Published over Relational Data: A Round-Trip Case Studystudied in the last few years. Updating such virtual XML views, however, is not well studied, although it is essential for building a viable full-featured XML data management systems. XML view update is a challenging problem because of having to address the mismatch between the two rather different

A Redundancy Free 4NF for XMLn helping to improve the semantic expressiveness of XML. Functional dependencies (FDs) and multivalued dependencies (MVDs) play a fundamental role in relational databases where they provide semantics for the data and at the same time are the foundation for database design. In some previous work, we

Repairs and Consistent Answers for XML Data with Functional Dependenciesor computing repairs (minimal sets of update operations making data consistent) and consistent answers. More specifically, our repairs are based on i) the replacing of values associated with attributes and elements, and ii) the introduction of a function stating if the node information is reliable.

https://doi.org/10.1007/978-1-4615-9089-7We present algebraic equivalences that allow to unnest nested algebraic expressions for order-preserving algebraic operators. We illustrate how these equivalences can be applied successfully to unnest nested queries given in the XQuery language. Measurements illustrate the performance gains possible our approach.
