Data Historians – Real-Time Data Capture
Modern data historians offer sophisticated features enabling organizations to capture and access data from disparate sources.
- Connectivity – Historians use standard protocols such as OPC and ODBC to easily integrate with data sources, including DCS, SCADA, PLC, and Database systems
- Scalability – Historians can be sized according to the scale required and expanded as requirements change. Historians can be configured to support hundreds of thousands of real-time data streams.
- Performance – Data archival is optimized and can be captured based on exceptions (when data changes), deadband, or periodically. Retrieval performance is typically very fast, and access can be provided to enterprise systems or users
- Reliability – Historians use sophisticated technology to ensure data integrity and prevent loss during communication failures. Redundancy and failover capabilities are commonly implemented to ensure consistent system operation.
- Management – Historians provide intuitive ways of managing data sources and tags along with system management tools for monitoring performance and processes
- Calculations – Historians provide capabilities to configure calculations that use data gathered from one or more data sources
- Historians may well be the original Big Data platform providing the capability to capture and access millions of transactions over many years
- Long-term data storage allows operations to refer to historical events that build organizational knowledge
- Fulfills regulatory requirements for data capture
- Cost-effective and efficient means for capturing vast amounts of data
