GRASP: A Complete Graphical Conceptual Language for Definition and Manipulation of Statistical Databases
Abstract
Recent research activities show a growing interest in statistical databases. Such interest is motivated by the increasing number of statistical applications and the inadequacies of traditional database languages and interfaces for statistical applications.
An outstanding open problem in statistical database development is how to express aggregate data starting from a description of elementary data. We propose a solution to this problem by means of a new language, called GRASP (GRA phical Statistical Package). The language allows to query uniformly both elementary and aggregate data; and is, therefore, suitable for several different purposes: a) posing queries on elementary data; b) building aggregate data from elementary data; c) computing new aggregate data using statistical operators.
