Top Features Of Teradata

What is Teradata?

Teradata is a widely used RDBMS, a relational management of databases (RDBMS) it can be identified for its distinctive capabilities, including constant in its data and transactions with a wide range of security features, exceptional in parallelism, high in performance, strong and robust structure, higher performance, scalability and ease of use, to provide SQL querying, etc. The main components are Storage Architecture, AMPs or Access Module Processors, Parsing Engine and a corresponding Message Parsing layer.


Unlimited Parallelism: Teradata is based on MPP architecture (Massively Parallel Processing) that divides the work equally across all the systems. It splits the job among its processes and executes them in parallel. This eases the pressure and task is completed in record time.
Connectivity Teradata is able to connect with mainframe systems or network-attached systems. It supports SQL to connect to the data in the tables. Additionally, it provides the extension it owns.
Mature Optimizer: Teradata Optimizer is extremely advanced and is working parallel from the beginning.
Linear Scalability: Teradata systems are highly flexible. They can be scaled up at 2048 instances. One could easily triple power of the device by tripling its number AMPs.
robust Utilities: Teradata supports robust utilities for importing and exporting data. Examples include: Fast Load, Multi-load, etc..
Shared Architecture of Nothing: Teradata nodes, AMPs work independently without sharing. They operate independently.
Useful for any type of person: it could be customized for any kind of user such as business as well as application users. Teradata SQL client can be tailored to meet business requirements and comes with great features for business requirements.


The principal components are Parsing Engine, ByNet The Access Module is the main Processors. The following are the most important components of the system:


Each server in Teradata is known as a “node. Each node is equipped with an operating system of its own, memory, CPU, disk space and their own version of Teradata’s RDBMS. A cabinet of a Teradata would contain an array of the numbers of Nodes.

Parsing Engine

Parsing Engine is utilized to get requests from the client and for preparing a detailed execution plan. The parsing engines responsibilities are:

Receiving SQL queries from the client
Input the query you received into the system and look for any syntactical mistakes
Make sure that the user is granted the permissions required for objects used in the query.
Make a detailed execution plan, get the query and pass the SQL query to BYNET.
In order to receive the results from AMP and send the results to the client

Layer for Message Parsing

It is also known as BYNET. It is the network layer of the Teradata system. It is used for communication between nodes and between PE as well as AMP.

Access Module Processor

The AMPs can also be described in other ways as virtual processors. They are the ones that actually stores the data and retrieves the data.

Storage Architecture

Let’s take a look at how storage processing occurs in the system.

When a client enters a query for inserting records the records are sent to ByNET by an engine for parsing. BYNET is able to retrieve the records and sends the rows to the AMPs that are targeted for. The AMPs database stores the data on the disk.

The process of retrieval

When a client executes queries to get the records first, the parsing machine makes a request to ByNET. BYNET sends the request to the appropriate AMPs. The AMPs will then look through their disks in parallel , and locate the needed record and send this to BYNET. ByNET would then transmit the records to parsing engine which again would send them to the client , and complete the process.

When should you decide

If we require a highly efficient, high-performance, scalable and massively parallel data warehouse system We chose Teradata.

There is no need to select Teradata when the need is only searching for data and loading data from multiple situations etc…

Teradata Security

It offers a high level of security, such as both user and system level security for passwords, row and column level security, user authentication.

What do you need to be aware of if you wish to take advantage of Teradata and make it a job option?

It is RDBMS it is DBMS software that helps to interface with data tables through SQL. A basic understanding of DB such as SQL querying or any DB languages can aid you switch to Teradata use. However, one needs to be extremely creative in order to become a Teradata professional, and also be capable of writing queries that are scalable and efficient.

But, the job opportunities for an Teradata technician are a limited as the majority of companies use Teradata for only large-scale applications.
