The problems of building the data model of information-analytical system (IAS) with the use of tensor methodology developed in the works of Crohn’s. Preconditions for the use of tensor calculus formalized description of the data model. Proposed assignment and conversion of the bases of multidimensional spaces subject as index moving objects with indices on the top (the system) level model representation. For a detailed description of all the objects of the multidimensional space of subject (the entity), introduces a set of fixed indices. In this case, any object model can be represented in a multidimensional space as an index of the first object valence, containing a set of fixed index and a sliding index. Invariants are defined spaces in the data allowing to analyze data structures. We solve the problem of estimating the amount of data stored in the transition from one type of space to another.
