Applied Physics and Mathematics Annotation << Back THE TRANSFER OF LEGACY INFORMATION SYSTEMS IN DOMESTIC OPERATING ENVIRONMENT A.S. KUZMIN, A.A. ROMANOV The problem of «legacy information systems» with import substitution in the sphere of information and communication technology is due to the use of foreign software and hardware platforms. Properties of software portability between operating Wednesday and interoperability of heterogeneous information systems Wednesday (interoperability) acquires particular relevance during this period. Shows the importance of developing domestic regulations and technological tools for interoperability levels for translating legacy systems into the domestic operating Wednesday. The necessity of coordination of sectoral programmes of import substitution in the framework of the national programme to ensure portability and interoperability of software operating Wednesday, hardware and software and information systems. The solution to the problem of inherited operating Wednesday linked to the implementation of measures to the evolutionary translation through trusted hardware and software Wednesday in domestic operating Wednesday in transition) period of import substitution. Keywords: legacy operating environment or system information, import substitution, portability, interoperability, porting the software operating environment, software analogue stages ensure portability and interoperability.
