In this paper we deal with the problem of security of statistical databases, i.e. file systems. We propose a model of a statistical database in which to investigate the properties of statistical databases and we describe a query language connected with such a database. We discuss the problem of dependencies between attributes and we consider the case when database contains incomplete information. In the case of incomolete information the problems arrive with the interpretation of the query language, mainly for statistical terms. The need for a orecise semantic is here evident.
