In this article, as a result of the analysis, it was revealed that attributive access control should be applied in heterogeneous Big Data storages. Then, an algorithm for transferring rights between different data models that are part of heterogeneous Big Data storages was formulated. The limitations imposed on this algorithm are also revealed. Thus, the task of implementing a method for managing rights in heterogeneous Big Data repositories has been completed.

Currently, attempts are underway to implement a temporal database management system. Such systems should take into account the possibilities of temporal support. This article discusses how to build temporal databases. The implementation of the time model for temporal add-ons of the database management system is presented for the project organization. Entity chart developed, which reflects the database tables and their relationships. Entity classes created. They correspond to tables from databases in individual files. Methods are presented that translate temporal requests into relational ones.

Failure of communication equipment and automated control systems by the fire of the State Fire Service of the Ministry of Internal Affairs of the Russian Federation, leads to a significant reduction in staffing it and, as a consequence of this, to the disruption of assigned tasks. Proposed generalized analysis allows to take into account all the factors affecting the recovery process as a single sample and the communication system and create a conceptual model of the recovery process communication equipment repair bodies of technical communications and automated control systems of the State Fire Service of the Ministry of Internal Affairs of the Russian Federation.

Failure of communication equipment and automated control systems by the fire GPS MES of Russia, leads to a significant reduction in staffing it and, in consequence, to the disruption of assigned tasks. The proposed conceptual model and its verbal description allowed to identify bottlenecks in the process of restoring the vehicle to repair the organ, and in its financial support in the form of appropriate repair kits of spare parts, as well as its efficiency in the reduction of the distribution group damaged samples according to multiplicity created ZIP.
