The work is devoted to the composition model requirements of the information system at the stage of database conceptual modeling. To formalize the description of the requirements were used different types of functional and non-functional requirements that were identified during analysis of a variety of pre-analysis techniques. Based on the concepts of entity and attribute database, were modeled relations between requirements and other components of the conceptual model. The proposed model allows to support the developer on stage composition of system requirements during the conceptual database modeling.
