We investigate a class of path constraints that is of interest in connection with both semistructured and structured data. In standard database systems, constraints are typically ...
We study similarity queries for time series data where similarity is defined in terms of a set of linear transformations on the Fourier series representation of a sequence. We ha...

Translating data and data access operations between applications and databases is a longstanding data management problem. We present a novel approach to this problem, in which the...
Query processing techniques for XML data have focused mainly on tree-pattern queries (TPQs). However, the need for querying XML data sources whose structure is very complex or not...
