Teradata relies on three architectural components.
Parsing Engine (PE)
The Parsing Engine (PE) is a component that interprets SQL requests, receives input records, and passes data. It sends the messages through the BYNET to the AMPs.
BYNETs
The BYNET act as message-passing layer. It decides which AMP should receive a message.
Access Module Processor (AMP)
The AMP is a virtual processor (vproc) designed to managing a portion of the entire database.
It performs all database management functions such as sorting, aggregating, and formatting data.
The AMP receives data from the PE, formats rows, and distributes them to the disk storage units it controls. The AMP also retrieves the rows requested by the Parsing Engine.
Disks
Disks are disk drives associated with an AMP that store the data rows.
