One of the common questions is: What is the difference between a data point and a data series?
Database terminology refers to the series as a series of several data points, which is slightly different from our terminology. By one data point is meant a data series - a series of samples of one data point, which represents the values obtained by measurement from the technological process. Standard database licensing is based on the number of data points (series) used, ie the database is not licensed according to the number of samples, but according to the number of series of data points. Sampling of a process variable is continuous within one data series.
The standard Merbon DB 40,000 license means that it is possible to store 40,000 data series - series of samples - data points.
