Abstract. The overhead of matching CHR rules is alleviated by constraint store indexing. Attributed variables provide an efficient means of indexing on logical variables. Existing ...
We solve the problem of obtaining answers to queries posed to a mediated integration system un der the local-as-view paradigm that are consistent wrt to certain global integrity...
Two operations commute if executing them serially in either order results in the same change of state. In a system in which commands may be issued simultaneously by different use...

This paperdescribes the use of a powerful graph query language for querying programs, and a novel combination of transformations for generating efficient implementations of the q...

We introduce an LTL-like logic with atomic formulae built over a constraint language interpreting variables in Z. The constraint language includes periodicity constraints, comparis...
