Working with Historical Events/Values
Iotellect Server keeps acquired values and receives events from various devices and data sources. Some additional events and value updates come from internal sources, such as models.
Selected events and value updates are persistently stored in the server database. Note that for the sake of unification, Iotellect Server also keeps historical value updates in the form of events. These are special change events.
 | All those persistent events and persistently stored variable value updates are referred to as historical data. |
Working with historical data is an important part of most Iotellect projects. This section provides a comprehensive reference on all tools, instruments, and methods for storing and processing historical data.
Historical data processing involves several major aspects:
-
Configuring storage of historical events and variable values
-
Configuring aggregation of source events/values and storage of aggregated data
-
Acquiring raw historical events and values
-
Acquiring aggregated historical data
