Russell, George and Neumüller, Mathias and Connor, Richard (2003) TypEx: a type based approach to XML stream querying. In: Proceedings of the International Workshop on Web and Databases (WebDB' 03). WebDB, pp. 55-60.
We consider the topic of query evaluation over semistructured information streams, and XML data streams in particular. Streaming evaluation methods are necessarily eventdriven, which is in tension with high-level query models; in general, the more expressive the query language, the harder it is to translate queries into an event-based implementation with finite resource bounds.
