Information Subsystem of Data Integration between DBMS Oracle and DBMS HyTech

The work is devoted to the creation of a subsystem of data integration between the DBMS HyTech and the Oracle DBMS. This subsystem of integration is developed and maintained specifically for the state non-profit fund of the Russian Federation (GNF RF).This project is a specialized development for a specific customer. When creating the integration system, special features of the work of the GNF of the RF were taken into account. The subsystem is an integral part of the data integration system between the general information system (OIS) of the state non-profit fund of the Russian Federation and the software product Parus 8. Initially, the information system for the GNF was operated by the HyTech DBMS, the functionality of which is currently insufficient to ensure sustainable development of the system. The data integration subsystem is created to implement the process of transition from the HyTech system to the Oracle DBMS. Currently, the developed subsystem of data integration is implemented and used by the customer in daily work. The final result will be the transition from the HyTech system to Oracle. These changes will allow you to upgrade to a more modern database, which will have better standardization and scalability. Explanatory note to the work contains 62 pages.
