Answer to Question 1

Data can be collected for a BI system in two ways. First, the data may come from an operational database that contains the data from the operational processes in a company. Second, data may come from other sources that are then combined with operational process data. In either case, once the data are collected they are then prepared and stored in a data warehouse, a repository for the organization's BI data. BI data are kept in a data warehouse because a data warehouse is specially designed to make sorting and retrieving large volumes of data efficient.
