Link data fields

Data items included in a data view may have slight differences in property naming, despite those properties representing the same logical thing. For example, data from one equipment manufacturer reports Temperature, while another reports Temp instead.

Data views can overcome property naming differences by linking these similar properties into a single data field. This applies to stream properties referenced by Id or by name, and to stream metadata keys.

When data fields are linked, CONNECT converts the data types in the linked fields into compatible data types. For more information, see Data view data type conversion.
