Data view in Side Panel

Does anyone know why I cannot see the Data view in the side panel under workspace.  I see catalog instead of data.  Is this something that has been upgraded?

@SamAWS - when you want to query the underlying data in the dataframe by creating a view or table, Spark SQL is preferred. Same can be achieved using pyspark by retaining them as a dataframe. Spark SQL is used by wider audience and easy to develop.
