Problems of integration of corporate information systems — methods and technologies

Lebedev Aleksandr Sergeevich

The article considers the problems of integration of corporate information systems (IS) in the conditions of metallurgical holdings. The structure of the levels of integration of corporate IS and the resource planning system of the enterprise, as a central module of the IT landscape, are presented. The structure of general integration approaches is proposed at different architectural levels of IS, providing a uniform, unified presentation of data from different sources and taking into account different types of heterogeneity of IS. Various integration approaches are analyzed in accordance with the level of abstraction at which IS integration is performed. It is shown that explicit and accurate semantics of integrable data is important for semantically correct and meaningful integration results.
