The aim of this work is the formation of holistic and reliable representation of technological complex (TC) in all phases of its life cycle in Integrated Information System (IIS) of company. The main components of architecture are implemented using information system (IS) Gellish and SAP products, such as SAP MDM, SAP CE, SAP PI, SAP HANA. For Information model creation, that is independent of data storage model, semantic modeling technique Gellish was adapted. In 2012 the first edition of templates for energy facilities and drilling rigs using IS Gellish was designed, in 2013 a prototype of the well was intended, and in 2014 plans are to implement OMD-storage based on SAP HANA, in 2015 as a part of a pilot management system it is planned to approve master data on energy facilities and drilling rigs in an Integrated Information System of the Company. Implementation of described architectural decision will solve the problem of semantic integration of data on technological complex between various information systems of the company, and will ensure the required quality of data on a technological complex in the Integrated Information system of the company.
