Industrial Automatic Control Systems and Controllers Annotation << Back High-performance Data Historian of Supervisory Control and Data Acquisition A.V. Zamyatin, P.M. Ostrast, E.A. Telitsin, V.N. Trenkaev, V.D. Janowskyi The article presents the results of research on high-performance data historian server design. Data historian server performance evaluation technique is proposed and tested. The experimental model of the data historian server using OPC UA model of workload performance is tested. It is shown that data historian with proposed architecture can provide the quality of service in terms of computational performance required for up-to-date SCADA systems. Keywords: SCADA; OPC UA; DBMS; DB; data historian server; key-value store; time series; computational performance.
