Glava M. Information technology of integration of heterogeneous databases on the base on the association of models of subject domains

The thesis is devoted to solving the problem of integration of heterogeneous databases based on association of models of subject domains. The research proposes the methods of analysis of objects and their properties of combining models of subject domains, the method of integration of integration models of individual subject domains based on agreed rank assessments of objects and the values of their typed essential properties. The model of the object of the subject domain is improved, which, unlike the classical one, takes into account the integration components important in the combination: the set of values of the agreed ranks of properties, and the sets of typed substantive and non-essential properties of the object and their meanings are determined on their basis. The model of the subject domain is improved, which, unlike the existing one, takes into account the defined association scenario and the agreed rankings of the objects. Based on the proposed models and methods an information technology for the integration of heterogeneous databases has been developed. It allowed increasing the reliability of the definition of objects of subject domains and their properties to be combined, while simultaneously reducing the number of operations of their comparison in the automated creation of the integrated integration model of the subject the domain. Keywords: database, subject domain, object domain, domain model, object model of the domain, object properties.
