Databases model for determining of technological features based on the theory of technological similarity

The main achievements presented in this paper are developed method orientated on computer aiding and computer program method, both used in designing process of the new technical features. Analyzed methods develop algorithmisation of selection features and support integration with the process of the preparation of the production. Further analyses will be carried on in order to specify the theory of the technological similarity in the new forms of computer aiding (relational databases). The represented programs were being developed on the practical examples of creating the module systems of hydraulic cylinders used in mining, slag cars used in metallurgy and gears series of types. Programs and data bases presented in the paper are basis of selection of the technological features in the process series of types of the technology creating. All of these applications support the intensive development of the types of technical features and affect on their competitive on the ready market.
