Answer to Question 1

TRUE

Answer to Question 2

Online analytical processing (OLAP) systems allow users to interactively retrieve meaningful information from data, examining it from many different perspectives and drilling down into specific groupings. The software allows users to slice and dice massive amounts of data stored in data warehouses to reveal significant patterns and trends. OLAP systems help spot suspicious activity as well. Medicare anti-fraud strike forces, for example, use such systems to detect unusual billing that might point to illegal scams. OLAP systems achieve their speed and their slice-and-dice capabilities by building multidimensional cubes. These are data structures that contain detailed data, and also aggregated values for the dimensions, metrics, and hierarchies the users need.
