Solution
The primary reason a company would want to have a Data Warehouse is to enable data analysis, check trends, and make high-level decisions. A Data Warehouse is a system used for reporting and data analysis, and is considered a core component of business intelligence. They are central repositories of integrated data from one or more disparate sources, which stores current and historical data in one single place. This allows for comparisons, patterns, and trends to be viewed over long periods, which in turn, helps in strategic decision making in the company.
While the other options like taking snapshots of data for recovery purposes, archiving data for future audits, and having physical storage for disks and tapes might be part of a company's data strategy, they are not the primary reasons for having a Data Warehouse.
