View Column Dependencies and References
TDV provides API tools for you to ascertain the data lineage of the resources involved in a query. You can determine:
Column dependencies—How the columns are derived from a specified composite view and going back one or more levels through the various resources on which the view depends. You can find out what resources are involved and what transformations might have occurred that affect the results. See Getting Column Dependencies Using the API, for more information.
Column references—What resources directly depend on that column. You can find out what other views refer to a specific column in a table or view. See Getting Column References Using the API, for more information.
