Historian databases are designed to capture and store large amounts of time-series data from multiple sources. They can be used for real-time monitoring, analysis, and reporting of process variables such as temperature, pressure, flow rate, etc. Data Historian servers provide an efficient way to access this stored information for further analysis or reporting purposes.
On the other hand, a database server is designed to store structured information such as customer records or product catalogs. It provides an efficient way to access this stored information for further analysis or reporting purposes. The function of a historian server is different from that of a database server as it stores time-series data instead of structured information.
