Interoperability Application Package

To simplify the solution of the problem of ensuring the ability to interact with ready-made software systems, the paper considers the creation of a set of interconnected modules as tool software. When developing a set of interconnected modules to ensure interaction between software systems at the physical level, it is proposed to use CALS technologies, at a logical level, a program for frequency data identification. The developed modules allow to reduce the time needed to create a single data warehouse using PDM technology and to ensure the interaction of software systems using standard CALS interfaces and a frequency data identification program.
