Processing a twig pattern query in XML document includes structural search and content search. Most existing algorithms only focus on structural search. They treat content nodes th...
Finding all the occurrences of a twig pattern in an XML database is a core operation for efficient evaluation of XML queries. Recently, Lu et al. [7] proposed the TJFast algorithm ...
To address the needs of data intensive XML applications, a number of efficient tree pattern algorithms have been proposed. Still, most XQuery compilers do not support those algori...
In deletion propagation, tuples from the database are deleted in order to reflect the deletion of a tuple from the view. Such an operation may result in the (often necessary) del...
