It is good to have options, but the large number of options for data warehouse modernization can be overwhelming. To give business and technology people the information they need prior to deciding where to focus modernization, this report discusses data warehouse infrastructure, highlighting the components that are currently high priorities for data warehouse modernization.
Note that data warehouse modernization is seldom for its own sake. In a few cases, updating a warehouse may be done for technology reasons, as when a database or hardware upgrade increases warehouse capacity or query response speed. In the majority of cases, however, there is typically a business reason that “trickles down” to the warehouse. For example, many business people are demanding advanced analytics and self-service data practices, which in turn demand data provisioned in new and unique ways by a modernized data warehouse.
