3.1
Real-time database real-timedatabase
A database specifically designed to process and store values and status variables over time.
3.2
Measuring point
A storage unit of time series data in real time database.
NOTE Point data may be derived directly from the acquisition equipment or from non-acquisition equipment such as statistics.
3.3
Quality code (status code) qualitycode
A set of codes describing data quality attributes, each in 32-bit total.
3.4
Real-time value currentvalue
The latest value collected by the measuring point, that is, the value closest to the current time stored in the measuring point in the real-time database. Each real-time value includes the timestamp, number
According to the value and quality code three parts.
3.5
Historical value historicalvalue
The historical value collected by the measuring point, that is, the non-latest value stored in the measuring point in the real-time database. Historical data is formed by precipitation of real-time data, each calendar
Historical value includes time stamp, data value and quality code in three parts.
3.6
ResultSet resultset
Call the real-time database common interface returns the resulting data collection, the results of the data format defined by the contents of the query.
