Introduction
Teradata RDBMS is a complete relational database management system. The system is based on
off-the-shelf Symmetric Multiprocessing (SMP) technology combined with a communication
network connecting the SMP systems to form a Massively Parallel Processing (MMP) system.
BYNET is a hardware inter-processor network to link SMP nodes. All processors in a same SMP
node are connected by a virtual BYNET. We use the following figure to explain how each
component in this DBMS works together.
Teradata File System:
It allows Teradata RDBMS to store and retrieve data regardless of low-level operating
system interface.
PE (Parsing Engine):
Communicate with client
Manage sessions
Parse SQL statements
Communicate with AMPs
Return result to the client
AMP (Access Module Processor):
BYNET interface
Manage database
Interface to disk subsystem
