Ontological domain description based synthesis of the data schema for information system

The paper presents a methodology based on the use of the process approach and object-oriented analysis to create domain ontology for information system, which is subsequently mapped in its data schema. The developed technique allows to formally define the reusability condition of existing components library of information system, to automate library expansion, to solve upgrades and maintain problems for the set of implementations of systems that are replicated and used in business processes of different companies.
