Classifying data

Please examine the airdelayspredict.csv file that you created in Chapter 9, Integrating Azure Cognitive Services and Machine Learning. You will find a schema classification on the Overview tab or in the Schema view: U.S. Stage Name for DEST_STATE_ABR and ORIGIN_STATE_ABR. This is one of the predefined classification rules that are available in Purview.

Let's discover where you can find them and how you can add your own classifications and classification rules.
