Answer to Question 1

TRUE

Answer to Question 2

An operational database is used for structured transaction data processing, while a dimensional database is used for unstructured analytical data processing. An operational database uses current data, while a dimensional database uses both current and historical data. With an operational database, data are inserted, modified and deleted by users, while for a dimensional database, data are loaded and updated systemically by the data warehouse administrators.
