The pressure to leverage data as a business asset is stronger than ever. Enterprises everywhere are eager to devise sound data strategies that are realistic and achievable, based on available budget and sensitive to in-house technology skill sets. Recent advances in storage costs and compute scalability issues, especially in the cloud, have addressed the most important challenges previously faced by Data Warehouse platforms. We are in a Data Warehouse (DW) renaissance period. Problems with Data Warehouses have largely been solved, petabyte-scale data volumes no longer defeat them and the familiarity and ease of use that kept them viable all this time are now helping them face their open source big data competition and, in many cases, emerge victorious.
