A major technological trend for large database systems has been the
introduction of ever-larger mass storage systems. This allows
computing centers and business data processing installations to
maintain on line their program libraries, less frequently used data
files, transaction logs and backup copies under unified system
control. Tapes, disks and drums are classical examples of mass
storage media. The more recent IBM 3851 Mass Storage Facility, part
of the IBM 3850 Mass Storage System, represents a new direction in
mass storage development, namely, it is two-dimensional. With the
maturity of magnetic bubble technology, more sophisticated,
massive, multi-trillion-bit storage systems are not far in the
future. While large in capacity, mass storage systems have in
general relatively long access times. Since record access
probabilities are usually not uniform, various algorithms have been
devised to position the records to decrease the average access
time. The first two chapters of this book are devoted mainly to
such algorithmic studies in linear and two-dimensional mass storage
systems. In the third chapter, we view the bubble memory as more
than a storage medium. In fact, we discuss different structures
where routine operations, such as data rearrangement, sorting,
searching, etc., can be done in the memory itself, freeing the CPU
for more complicated tasks. The problems discussed in this book are
combinatorial in nature.
