What is Teradata?
It is a database that is designed to handle queries. It is a relational database management system for the world’s largest commercial databases. Other RDBMS takes enormous time to process and execute the data. But Teradata RDBMS handles a massive amount of data with ease. Its scalability, parallel processing, and high performance are the main attraction. It generates an optimal plan for the query within a few seconds. Teradata can save up to Teradata bytes in size. The concept of parallelism makes It the industry giant in data warehousing applications. It is based on shared-nothing architecture.

Teradata Career Architecture and Components
The architecture of Teradata RDBMS is designed using shared-nothing architecture.
Teradata Career database systems are of two types:
- SMP (Symmetric Multi-Processing)
- MPP (Massively Parallel Processing)
SMP system is a single NODE system with multiple CPU-sharing memory pools. MPP system has two or more NODES connected by a component called BYNET.
Teradata architecture contains the following components:
This is the collection of hardware and software components and the building block of its database system where the processing occurs. Channel system and network system can be integrated with NODE.
Parsing Engine (PE) is a component that interprets SQL requests receives input and transforms the data. The data is transferred through the BYNET to the AMP.
Parallel Database Extension (PDE) runs the operating system on each NODE. It runs Teradata Career Component in parallel.
Access Module Processor (AMP) is a virtual processor designed to manage the database. It sorts, aggregates, and formats data. Each AMP is associated with one virtual disk where there is data stored. It helps to retrieve or update data.
5. System disks
System disks are a part of the NODE that stores data rows. It includes:
The activities of the database are stored on disk arrays.
6. VPROC (Virtual Processor)
VPROC combines one or more software processes in the OS multi-tasking environment. In Windows OS, VPROC is a single software process. The two types of VPROC are AMP and PE.
7. BYNET (Banyan Network)
BYNET combines hardware and software that provides high-performance networking between the NODES. BYNET is a message-passing layer. It helps the NODES to communicate in a faster way. BYNET hardware and software components handle the communication between the VPROCs. The hardware of BYNET includes boards and cables. The software of BYNET consists of an interface between PDE and BYNET hardware.
The essential features of BYNET include the following:
- Fault Tolerance
- Load Balances
- High Scalability
Teradata Career Data Warehouse System Components
The following are the components:
1. Teradata Database Server
Its Database Server manages a large number of data. It helps in scalability and ensures the integrity of the data.
The database has several modules, which are mentioned below:
- Teradata Database Window – Has control over the operation of the Teradata Career Database
- Teradata Gateway – Controls communications, client messages, and encryption
- Parallel Data Extensions – Enables parallel processing in the Database
