We study conjunctive inductive queries, which are queries that can be written as a conjunction of a monotonic and an anti-monotonic subquery. We in- troduce the ...

The optimization problem for conjunctive queries has been studied extensively. Unfortunately, this research almost invariably assumes set-theoretic.

But for conjunctive queries, even e1 ⊆ e2 is decidable. • Main goal of optimizing conjunctive queries: reduce the number of joins. Beijing. 2. Topics in ...
Techniques to optimize relational queries are based on transforming a given query into a query that is semantically equivalent but less expen- sive to evaluate.
