Database systems always involve secondary storage——the disks and other devices that store large amounts of data that persists over time. This chapter summarizes what we need to know about how a typical computer system manages storage.We review the memory hierarchy of devices with progressively slower access but larger capacity.We examine disks in particular and see how the speed of data access is affected bu how we organize our data on the disk . We also study mechanisms for making disks more reliable.
