Data Historian

A specialized database designed to collect, compress, store and retrieve time-series operational data from industrial systems.

Definition

A Data Historian is a software system optimized for collecting and storing high-frequency time-series data generated by process control systems, sensors, instrumentation and industrial equipment. Historians provide efficient long-term storage, trend analysis and retrieval of operational data used for performance monitoring, condition monitoring, troubleshooting and advanced analytics.

Why It Matters

Data Historians preserve operational history, enabling engineers to analyze process performance, investigate incidents and support reliability improvement initiatives.

In Practice

Data Historians commonly integrate with DCS, SCADA, PLC and IIoT systems while providing interfaces for reporting, dashboards, analytics and enterprise applications.

Common Misuse

A Data Historian stores operational time-series data and should not be confused with engineering document management systems or relational asset information databases.
