In the realm of data archiving, time-series data management is a critical component for efficient process operations. The openHistorian stands out as a robust back-office system that excels in integrating, storing, and retrieving massive volumes of process control data. This article serves as a guide to understanding how to deploy and troubleshoot the openHistorian system effectively.

Overview of openHistorian

The openHistorian is designed to work with various types of process control data, such as SCADA or synchrophasor data. It utilizes the GSF SNAPdb Engine, which employs key-value archiving technology for optimal performance.

To better comprehend the functionality, let’s use an analogy. Think of the openHistorian like a sophisticated library that holds thousands of books (data) about real-time events. Each book is meticulously cataloged—organized not just by title (measurement ID) but also by the time each book was written (timestamp). This organization allows for rapid access and retrieval of specific information, ensuring that when a user asks for a particular book (data point), they can get it with minimal waiting time.
