Answer to Question 1

FALSE

Answer to Question 2

When compared to operational information, analytical information has a longer time horizon. Given that a data warehouse contains analytical information, its time horizon is longer (usually substantially so) than the time horizon in the operational databases. The term historical refers to the larger time horizon in the data warehouse than in the operational databases. For example, many traditional operational databases have a time horizon of 60 to 90 days, where it is quite common for data warehouses to contain multiple years' worth of data.
