Chapter 10. Hardware and Operating Systems The term hardware and operating systems refers to the server platforms and operating systems that serve as the computing environment of the data warehouse. Warehousing environments are typically separate from the operational computing environments (i.e., a different machine is used) to avoid potential resource contentions between operational and decisional processing. Enterprises are correctly wary of computing solutions that may compromise the performance levels of mission-critical operational systems. The major hardware vendors have all established data warehousing initiatives or partnership programs with other firms in a bid to provide comprehensive data warehousing solution frameworks to their customers. This is very consistent with the solution integrator role that major hardware vendors typically play on large computing projects. Parallel Hardware Technology As we mentioned, the two primary categories of parallel hardware used for data warehousing are the symmetric multiprocessing (SMP) machines and massively parallel processing (MPP) machines. Figure 10-1 illustrates the architecture of these two machines.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
