Information technology for combining the relational heterogeneous databases using an integration models of different subject domains

Abstract

The work is devoted to solving the problem of combining heterogeneous relational databases based on integration
models of different subject domains. The paper proposes methods for analyzing objects and their properties when combining models
of subject domains, a method of combining integration models of different subject domains based on consistent rank evaluations of
objects and the values of their typed essential properties. The model of the subject domain object is improved, which, unlike the classical one, takes into account the integration components that are important for combining: the sets of values of consistent ranks of
properties and the sets of typed essential and non-essential properties of the object and their values determined on the basis of them.
The subject domain model has been improved, which, unlike the existing one, takes into account certain combining scenarios and
consistent ranking assessments of objects. Based on the proposed models and methods, an information technology for combining
relational heterogeneous databases has been developed, which has increased the reliability of detection of subject domain objects
and their properties to be combined, while simultaneously reducing the number of comparison operations for automated creation of
a combined integration model of the subject domain.
