The majority of the data warehouses in the Netherlands is between eight and twelve years old. During that period of time data warehousing has become accepted as the main architecture for providing information for reporting and analysis in support of decision makers. Unfortunately, the data warehouse was never designed to integrate the growing amounts of unstructured data, commonly referred to as “Big Data”.
But not only the data structure versus the setup of the data warehouse constitutes a problem. Big Data also challenges data warehouses as to the speed with which data becomes available, which is many times greater than data warehouses were supposed to handle. The question that therefore arises is: “Will data warehouse survive the Big Data challenges?”
