Beskrivelse
As the latest update in the popular Teradata Database trilogy, this book continues the fascinating journey into the nether-world of large-scale data maintenance and disaster recovery. Taken at face value, it discusses a succession of powerful utilities for the large-scale processing and recovery of huge amounts of data, and identifies the particular situations in which each, in turn, becomes a top performer in its class. Beneath the surface however, it reveals how Teradata covertly uses the concept of multiple sessions to induce a sequential-processing mainframe or PC to behave as if it were a parallel-processing device, and the many creative and innovative ways it employs those same multiple sessions to wring the very last droplets of performance from the powerful Teradata parallel-processing architecture. This book becomes an important supplement to those who can afford the luxury of a classroom education in the Teradata Database, and a valuable alternative to those who cannot.
