Location where data being used originates from. In ThinkIQ there are three data sources: Dynamic, Config, and Expression.

Dynamic data is usually time series data, also known in ThinkIQ as a value stream. Examples are data that come from a sensor.

Config data is usually static data - data that doesn't change, or rarely changes. For example, a geolocation, or a manufacturer part number.

Expression is a variation on dynamic, in that expressions operate on value streams - data over a specific time period
