In math, interpolation is a method of constructing new data points within the range of a discrete set of known data points. Ignition can use interpolation in a number of places, but it is notably used in the Tag Historian query system to intelligently generate additional values when the desired number of data points is greater than the amount of data stored in the database.
An Identity Provider (IdP) offers user authentication as a service. An IdP creates, maintains, and manages identity information for principals while providing authentication services to relying party applications within a federation or distributed network. Ignition 8 integrates with existing corporate identity infrastructures that use two-factor authentication (2FA).
