Teradata is a relational database management system designed specifically for large warehouse applications, based on Massively Parallel Processing (MPP) architecture. It optimizes query performance through parallelism, using the AMP as a basic unit. A pre-defined number of AMPs is shared across a Teradata system to perform tasks including queries, dataload, backups, index builds, etc. This allows for Teradata to have linear scalability for growing workloads.[03]
