"Classical" Analytical Data is derived from business operations and transaction data. It is mainly used to meet standard reporting and analytics requirements by applying descriptive analytics.
Advanced Analytical Data is created by applying methods of data science that go beyond purely descriptive analytics (i.e., towards predictive/prescriptive analytics). It is used to identify patterns or correlations in complex (structured and unstructured) data sets (including text and geospatial data, for instance).
