Regarding some approaches to creation of generalized architecture of Russian information space members of information systems

The article continues a publications line about regulatory and technical base forming for creation of Russian Federation Unified Information Space (RF UIS). The requirements to unified information systems architecture are in the article foundation. There are shown general propositions of systemic approach about architecture of information systems of organizations which are the members of RF UIS. The propositions regarding generalized architecture of RF UIS member information system and its possible typing are also presented. It is proved that unified information system generalized architecture should be focused on three interrelated segments: open, confidential, and closed. The segments must be considered as independent automated systems. The RF UIS organizations user groups are generally determined, including maintenance staff providing unified system functioning. Objective determination of unified information system architecture is given. It is based on three key points: fundamental approach to system, system rational structuring, and environment factors consideration. In the second point, the authors propose a general approach to determination of unified system component nomenclature (base systems, subsystems, networks, complexes, etc.) and their interrelations on principles of consolidation, integration, and centralization. There is an approach which presents unified information system of RF UIS member as two groups of base technological systems: Functions and Maintenance. The thesis of the article can be used as a scientific and methodological ground during regulatory and technical base forming of RF UIS members information systems creation.
