Shared-Nothing Architecture

The term shared-nothing architecture was coined by Michael Stonebraker (1986) to describe a multiprocessor database management system in which neither memory nor disk storage is shared among the processors. The PE and AMP vprocs in the Teradata architecture share neither memory nor disk across CPU units; therefore, Teradata is a shared-nothing database architecture. It is this architecture that affords Teradata systems their scalability.
