Explain about Teradata architecture

Question

Accepted Answer

Teradata architecture is a massively parallel processing (MPP) architecture designed for data warehousing and analytics.

Teradata architecture follows a shared-nothing approach.
It consists of parsing engine, BYNET, access module processors (AMPs), and disks.
Parsing engine receives SQL queries and generates an execution plan.
BYNET is responsible for interconnecting the parsing engine and AMPs.
AMPs store and process data in parallel.
Disks store the actual data in a distributed manner.
Teradata architecture allows scalability, fault tolerance, and parallel processing.
It supports high-performance queries and can handle large volumes of data.
