Data interchange between distributed systems components of aircraft lifecycle support

Features of an exchange and integration of data in geographically distributed systems are analyzed. We suggest to execute the centralized preliminary mailing of centralized identifiers arrays of copies regarding qualifiers and data coding systems, in cases of their changes, and also in case of plan extensions of integrable information resources of systems. A structural solution of devices is provided. The described approach allows to increase efficiency of a data interchange between components of geographically distributed system in case of execution of target tasks and to lower costs of its maintenance.
