Regardless of a company's size, if users are attempting to use transactional data to drive business decisions -- that is, if they're doing business intelligence (BI) -- they are implicitly or explicitly doing so by relying on data warehouse (DW) processes and practices. This in turn attests to the fact that any BI strategy must be tied to a DW strategy. Depending upon companies' unique conditions and circumstances, their BI strategies will utilize DW and DW tools at differing levels of sophistication.
