Using relational databases for organizations of controlled reverse engineering

Mechanical engineering is the main branch of industry, the level of its development determines the scientific and technical capabilities and potential of the country, determines the quality of human capital, and it is also the basis for maintaining the defense capability of the state. As a rule, for successful functioning, in this industry, opportunities for cooperation with counterparties are widely used both in the domestic and foreign markets. Currently, Russia is dependent on the products of foreign engineering, it is observed in all areas of this sphere - general, heavy, medium, light, precision and power engineering. Due to the increased sanctions pressure of unfriendly states, the possibilities of importing the necessary products and components are steadily decreasing. Of particular concern is the situation of dependence on imports of backbone and defense enterprises, as well as enterprises providing state activities. In this regard, it is necessary to accelerate the implementation of the import substitution policy with the use of reverse engineering. This method has shown its viability, because it was used by leading industrial powers. The purpose of the study is to substantiate the importance of reverse engineering as a tool for implementing the import substitution policy, to show the possibilities of its control and acceleration of the procedure for its implementation using a relational mathematical model. The relational mathematical model is based on the rules of relational algebra. Methods. The chronology of the emergence of Russia's dependence on imported components is revealed, the importance of reverse engineering is justified by the example of China's experience. Results. Russia's dependence on imports dates back to the Soviet Union. A relational data model for acceleration, organization and control of reverse engineering in Russia is proposed. Conclusion. The obtained research results may have practical application in the implementation of the import substitution policy carried out in the Russian Federation. The requirements for accelerating the implementation of the above-mentioned policy are justified by the narrowing range of opportunities for importing key components and products and the increase in foreign policy and foreign economic tensions.
