If we take control the following 5 points then we can say data from DWH is managed properly.

  • How can I ensure that my data warehouse is constantly available to its users?
  • What happens if the operating system, or disk, or database crashes? – Or the site gets burned down?
  • How can I tune the system on the fly?
    – In fact, how can I change the hardware configuration on the fly?
  • How can I spread the performance load across my global wide-area network?
  • How do I manage such an enormous amount of online and offline critical data?
