Adaptation of the attribute dependency model for designing a heterogeneous digital oilfield data warehouse

Abstract

The development of digital oilfield technologies has led us to the fact that there are virtually no production and management tasks left without any automated software solutions. However, the distribution, implementation, and use of individual IT-solutions often occur outside the rational automation strategy. At the same time, due to the complexity of the management object, due to the nature and composition of the tasks being solved, the lack of integration between the multitude of existing software solutions prevents the enterprise single information space formation. Thus, with the actual availability of critical information, the operational and strategic management tasks solution occurs without considering it. As a solution, the article considers an approach to creating a heterogeneous data warehouse based on an attribute dependency model that describes the relationship and interdependencies of data stored in distributed and heterogeneous sources. The article describes the interim results of a project to develop the architecture and software heterogeneous distributed data warehouse prototype for digital oilfield infrastructure.
