Abstract: The article presents the results of the development and experimental comparison of data structures and data storage methods. The basis for building the models included the financial market decision support system and expert evaluations of the electronic tendering system. In both cases the authors built conceptual data models, stored data in text files, relational and non-relational databases and evaluated efficiency of an organized structure from the point of view of efficient storage and access, automatic integrity control and data consistency. By using theoretical methods (abstraction, analysis, synthesis, and idealization) the authors developed conceptual database models. In its turn, by using empirical methods (experiment and comparison) they checked the efficiency of data storage with the use of text files, relational and non-relational databases. As the main conclusion of the research, the authors provide recommendations on how to select the best data storage structures for electronic decision support systems. The experimental comparison allowed to discover that for a developed expert evaluation storage structure the relational database control system is the most effective method while in case of storing information about financial markets, it is better to use text files for a developed decision support system.
