This tool grew exponentially, as more and more organizations are starting to collect and use a large amount of electronic data regularly. These four requirements control all decisions surrounding the settings and maintenance of a successful data warehouse.
Data warehouse requirements for device and hardware size can be very complex because these requirements depend on the combination of known and unknown factors.

Therefore, the minimum requiredThe space has reduced the facility, provided the device is renewed every year to the latest version.
