What does the History Table in the Runtime database contain?

The History Table in the Runtime database is specifically designed to contain all recorded values for a particular tag over time. This means it logs every significant data point that has been captured, allowing users to analyze trends, perform time-based queries, and retrieve historical data related to that tag.

The History Table is essential for data analysis, as it reflects the full range of data collected, which can include various statuses, events, and measurements associated with a specific parameter within a system. This thorough record-keeping enables users to perform comprehensive evaluations of system performance and behavior over a selected time frame.

Summarized data, multiple tags, and real-time processing information are not characteristic of what the History Table holds. Instead, these features may be managed in separate contexts or through specific data processing methods within the system architecture. For instance, summarized data might be found in summary tables designed for quick reporting, while real-time processing information pertains to the ongoing operations and immediate responses of the system rather than historical values.
