The paper analyzes the existing models of the various elements of the query to information-analytic systems content that has different forms of representation and methods of processing. The necessity of the existing models improvement in order to develop a model that provides a unified description of the data structures and electronic documents as the main content items of information-analytical system is proved. A mathematical model of query that provides typing functions of forming and processing of information requests to the content of the system is suggested.
