Abstract

In this paper the Authors propose a logical model (called GRASS) for representing both the properties of a Statistical Data Base (S. D. B.) and the tables view, which represent the peculiar reality of statistical user.The proposed model consists of a marked, labeled, direct, connected, acyclic, partially ordered graph. For this graph nodes semantics and connection andbranchingrules are provided. A cognitive and selective approach to how navigate through category attributes and summary data are given too. Finally, some facilities of the model are discussed and a comment is made.
