Teradata

Teradata Training 

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.
