(Cristian Molaro) In many situations, the speed at which analysts can understand and react to changes in a dynamic business environment is limited by the IT infrastructure’s ability to process complex queries against large volumes of data. Ideally, business analytics would be unconstrained by infras

(David Birmingham) Part 1 of this two-part series discussed the stresses on infrastructure, people, policies, processes, and protocols when the IBM PureData for Analytics powered by IBM Netezza technology first lands on the raised floor. We may know how to play the game.

(Craig S. Mullins) If you work with DB2 for z/OS and have to manage distributed workload… or if you are enabling zIIP specialty processors… chances are you’ve at least heard the term “enclave” or “enclave SRB” before. But do you understand what an enclave is and why it is important?

(Willie Favero) Today’s Fortune 500 companies are embracing distributed techniques to access mainframe data on DB2. Although online transaction processing (OLTP) workloads still dominate DB2’s local processing, more applications, such as data warehousing analytics, run remotely as distributed tasks.

(Whei-Jen Chen, Brigitte Bläser, Aidan Craddock, Polly Lau, Cong Lin, Kushal Munir, Martin Schlegel and Alexander Zietlow) DB2 with BLU Acceleration is a revolutionary technology delivered in DB2 for Linux, UNIX, and Windows Release 10.5.
