Querying Data with Irregular Structure

Natasha Alechina

(University of Birmingham)

I will give a survey of recent work on `semistructured data', that is, attempts to apply database methods to collections of information which do not conform to a fixed schema (such as heterogeneous databases, or fragments of the World Wide Web). I will also talk about some expressive power/complexity results for proposed query and description languages, and many open problems.
