Technical object (product) including radiotechnical type is a system consists of the elements and relationships between them. The purpose of this work: development methods of representation of structure of technical systems by oriented hypergraphs and ways of description hypergraphs in the relational database. Restrictions are imposed on elements of the system which determinated by domain and referencial integrity of database. The structure of relational database is concidered on example of hypergraphs with restrictions on their picks and edges. This structure allows to represent hypergraphs in software of informational systems and includes following objects: tables, primary and secondary keys, indexes, triggers. In relational database is carried out the analysis of events which can cause the losses in the referencial and domain in-tegrity of database. Recommended the objects of relational database (indexes, triggers) which can allow to maintain it referencial and domain integrity in a context of restrictions on picks and edges of hypergraph. Fragments of SQL program code are represented for the recommended objects. The developed methods are formed a basis for creating program templates which allow to decrease costs on building of program code of automated systems.
