The article considers the issues of creating a data warehouse the functioning processes of the electricity market for use in information modeling system that is a functional-oriented system and a part of decision support system in solving a set of computational problems for algorithmic modeling of the functioning of electricity market participants, analysis and prediction of their behavior in market segments. Based on the results of the analysis of researches on the decision support systems implementation, ways to improve the DDM-paradigm of creating such systems are formulated, among which are allocated the data structures modeling for the subject area of organizational management on the market. The paper on the basis of the object-oriented modeling principles for the functioning processes of the electricity market forms a representation of market participants and processes as a set of interacting information objects of the subject area. The description of the conceptual model for representation of the market functioning processes and results of designing of the information logical model of a data warehouse is given. The practical result of designing a data warehouse information logical model is the ability to create on its basis the physical structure of the object-relational database for the functioning processes of the electricity market, adapted to possible changes in the subject area of organizational management on the market.
