FIELD: information technologies.
SUBSTANCE: retrieval requests are generated dynamically on the basis of metadata, which describes type, composition, structure and tenancy of databases, and also on the basis of information specified in formed data pack of user request, identifying the necessary set of actions, sequence of their execution, required list of devices for execution, and also level of access for execution. Directly in data bases generated requests are serially executed, and a list of identifiers is made up for found objects, which satisfy search parametres, and in order to obtain and combine information, also on the basis of meta data describing data bases, a sequence of requests is generated dynamically to data bases to obtain information on objects found in various data bases and to transform it into a single format using principle of grouping according to types of objects.
EFFECT: improved efficiency of searching and receiving data on objects, and relations between them, data on which is available in diverse information arrays.
