Recursive aggregates - Semmle Limited

Apr 21, 2015 · This specification describes implementations of recursive aggregates, that is, of calls to aggregation functions inside of recursive queries, in query languages, e.g., SQL and Datalog, that evaluate recursive queries by iterating from the empty relation until a fixed point is reached, or that define recursion in that way.

Title: Grounding Recursive Aggregates: Preliminary Report

In this paper, we elaborate upon the treatment of aggregates during grounding in Gringo series 4. Consequently, our approach is applicable to grounding based on semi-naive database evaluation techniques. In particular, we provide a series of algorithms detailing the treatment of recursive aggregates and illustrate this by a running example.
