Abstract

Data warehouses (DWs) have become very successful in many enterprises, but only for relatively simple and traditional types of data. It is now time to extend the benefits of DWs to a much wider range of data, making it feasible to literally "warehouse the world". To do this, five unique challenges must be addressed: warehousing data about the physical world, integrating structured, semi-structured, and unstructured data in DWs, integrating the past, the present, and the future, warehousing imperfect data, and ensuring privacy in DW.
