- Operational_historian abstract "Operational historian refers to a database software application that logs or historizes time-based process data. Historian software is used to record trends and historical information about industrial processes for future reference. It captures plant management information about production status, performance monitoring, quality assurance, tracking and genealogy, and product delivery with enhanced data capture, data compression, and data presentation capabilities.Operational historians are like enterprise historians but differ in that they are used by engineers on the plant floor rather than by business processes. They are typically cheaper, lighter in weight, and easier to use and reconfigure than enterprise historians. Having an operational historian enables "at the source" analysis of the historical data that is not typically possible with enterprise historians.Typically, these applications offer two layers of data access: through a dedicated SDK(Standard Development Kit)(sometimes in two different flavours: full administration API(Application Programming Interface) and high-speed read/write API), as well as user front-end tools (for instance, administration panels, engineering consoles or portal-like web clients).Because these applications are designed to fulfil specific operation time requirements, their marketing materials often indicate that these are real-time database systems. However, since such performance measurements are often executed for atomic operations (especially write operations), not necessarily whole transactions, not all of the operational historians must be in fact real-time databases.Usual challenges the operational historians must address are as follows: data collection from real-time external systems, storage and archiving of very large volumes of data, tag organisation (typically time series, where a single sample contains the information about the time stamp, the value and the sample quality), basic data limit monitoring (alarms) and user prompts (messages), performance of read and write operations.↑ ↑ ↑".
