Query evaluation as constraint search; an overview of early results
We present early results on the development of database query evaluation algorithms that have been inspired by search methods from the domain of constraint satisfaction. We define a mapping between these two specialties and discuss how the differences in problem domains have instigated new results.
It appears that contemporary problems in databases which lead to queries requiring many-way joins (such as active and deductive databases) will be the primary beneficiaries of this approach. Object-oriented queries and queries which are not intended to return all solutions also benefit. Some obvious CSP interpretations of certain semantic database properties suggest open research opportunities.
