Association rules are essential data mining tool. There exist many types of them. Indeed, association rules of different types have often completely dissimilar syntax. In this paper, we try to design a framework based on relational operations enabling one to express various association rules using the same syntax. Doing so we will be able to study association rules at high level -- it will be possible to formally describe common characteristics of different rule types.
