Datawatch was one of the sponsors of a TDWI Report: Evolving Data Warehouse Architectures in the Age of Big Data. Among the findings... real-time data streams are becoming increasingly important to the business. Here is the abstract from the report:
Report Purpose This report educates users about the many directions data warehouse
architectures are evolving. Big data is a major driver of change with its burgeoning
size, sources, frequency of delivery, and diversity of structures. In addition, the
adoption of advanced analytics and real-time operation is equally influential on
DW architectures. To assist users, many new products and technologies have arrived
recently from software vendors and the open source community. This report describes
all of the above and more.
