Regular path queries (RPQs), expressed as regular expressions over the alphabet of database edge-labels, are commonly used for guided navigation of graph databases. While convenie...
In this paper we consider concurrent execution of multiple data mining queries in the context of discovery of frequent itemsets. If such data mining queries operate on similar part...
The development of a distributed database systemrequires effective solutions to many complex and interrelated design problems. The cost dependenciesbetween query optimization and ...
