François Bry, Michael Eckert:
Towards Formal Foundations of Event Queries and Rules.
Abstract
The field of complex event processing still lacks formal
foundations. In particular, event queries require both declarative and
operational semantics. We put forward for discussion a proposal towards
formal foundations of event queries that aims at making well-known results
from database queries applicable to event queries. Declarative semantics
of event queries and rules are given as a model theory with accompanying
fixpoint theory. Operational semantics are then obtained by translating
the considered queries into relational algebra expressions. We show the
suitability of relational algebra for the kind of incremental evaluation
usually required for event queries. With the aim of generating further
discussion of formal foundations in the research community, we reflect
openly upon both strengths and weaknesses of the presented approach.
