Abstract. Current proposals for designing information systems lack the mechanisms to define statistical functions at the conceptual level. Therefore, queries containing these kind of functions are defined once the rest of the system has already been implemented, which requires much effort and expertise. In this sense, the goal of this paper is to show the benefits of extending the Object Constraint Language (OCL) with a predefined set of statistical functions. 1
