Querying data sources that export infinite sets of views
Bogdan Cautis, Alin Deutsch, Nicola Onose · 2009
We study the problem of querying data sources that accept only a limited set of queries, such as sources accessible by Web services which can implement very large (potentially infinite) families of queries. We revisit a classical setting in which the application queries are conjunctive queries and the source accepts families of conjunctive queries specified as the expansions of a (potentially recursive) Datalog program.
