Data Warehouse in the age of Big Data
A Data Warehouse is a software architecture that for many years has been helping companies recover valuable knowledge from their different IT systems. The reality of the situation in which this technology is being implemented, however, has changed dramatically in recent years: These days, many companies are producing disproportionately more data and the associated reaction rates for analysing this information has been drastically shortened. Simultaneously, the thirst for knowledge on the part of companies and organisations has been increasing. This means classic Data Warehouse approaches are soon driven their limits. Big Data technologies promise to fulfil these new requirements and offer promising approaches to enhance and modernise the traditional Data Warehouse concept.
