Recursive queries have been traditionally studied in the framework of datalog, a language
that restricts recursion to monotone queries over sets, which is guaranteed to converge in …

A very desirable Datalog extension investigated by many researchers in the last 30 years
consists in allowing the use of the basic SQL aggregates min, max, count and sum in …

Recent years have seen a resurgence of interest from both the industry and research
community in Datalog. Datalog is a declarative query language that extends relational …

Modern data analytics applications, such as knowledge graph reasoning and machine
learning, typically involve recursion through aggregation. Such computations pose great …

In the past, the semantic issues raised by the non-monotonic nature of aggregates often
prevented their use in the recursive statements of logic programs and deductive databases …

A large class of traditional graph and data mining algorithms can be concisely expressed in
Datalog, and other Logic-based languages, once aggregates are allowed in recursion. In …

Relational databases have become one of the most important software components in the
world, ubiquitous in computing systems from smartphones to data centers. Nevertheless …

Cloud computing refers to maximizing efficiency by sharing computational and storage
resources, while data-parallel systems exploit the resources available in the cloud to …
