What is the function of the Historian OLE DB Provider in AVEVA Historian?

The function of the Historian OLE DB Provider in AVEVA Historian is to execute SQL queries to retrieve historical data. This provider serves as a bridge between applications that utilize OLE DB and the AVEVA Historian database, allowing users to access and manipulate data stored in the historian. By leveraging SQL queries, users can effectively obtain specific historical data, enabling them to perform analysis, generate reports, and visualize trends over time.

The OLE DB Provider is designed to facilitate flexible data retrieval methods, which are crucial for users who need to analyze past events or performance metrics. It enhances the integration of external applications with the historian, making it easier to pull the necessary data for decision-making processes.

While real-time data access is a component of historian functionality, it is not the primary role of the OLE DB Provider, which focuses on historical data retrieval. Managing security settings in the database and performing data backup operations fall outside the scope and intended use of the OLE DB Provider, as these responsibilities are typically handled by separate components or configurations within the historian server architecture.
