There are examined all documents and reports which exist in the subject area and it is proved that nested relations characterize the subject area the most adequately. By means of nested relations there is built the data model in the system "A district therapist". An analysis of subject domain of the information system "Pedagogical workers" allows to detect the complex entities the design of which by the classic relational data model does not provide necessary adequacy. The problem of presentation of the nested entities is successfully solved by nested relations. The scheme of database of the information system which consists of aggregate of nested relations is built, domains of all attributes are defined and also connections and dependences are described between attributes. The projected scheme can be used for program realization of the information system.
