Building an Enterprise Data warehouse (EDw)
- A company that is considering building a Dw first needs to address a series of basic questions to avoid a failure:
-- Does top management support the DW?
--Do users want access to a broad range of data
--Do users want data access and analysis tools?
--Do users understand how to use the DW to solve business problems?
--Does the unit have one or more power users who can understand DW technologies?
