In the age of Big Data, companies are using data-driven approaches to improve different aspects of their operations. Data from these companies is complicated large, massive, and constantly changing. It requires a reliable method to manage it. Teradata provides an open and flexible database management system that can enable businesses to enhance their results by using data management tools.

The Teradata system is utilized in many industries, including manufacturing medical care, manufacturing, and transportation to improve their processes. This article walks you through the Teradata system and will provide an overview of the various aspects, including the importance of features, the architecture, and features of Teradata. It also explains how Teradata is used and highlight its real-life applications.

Introduction

Teradata is an open RDBMS (relational database management system) that operates on operating systems like Windows, Unix, and Linux. Teradata supports huge databases and data warehouses. Teradata database offers a variety of choices to deploy. The system is able to support a variety of users on multiple platforms (concurrently). Teradata is a software application. Teradata runs on a parallel architecture.

It is a strategic intelligence platform that provides queries, intelligence tools, and utilities for strategic decision making. For instance, you can use Teradata to produce complex reports, such as business trends. These reports can be used to make accurate forecasts of the future that can improve decision-making within an business. Teradata provides tools for operational intelligence that improve front-line or operational decision making.

Why you should make use of Teradata

It can handle a huge amount of information (more than 50 petabytes).
It can be integrated into many Business Intelligence (BI) applications.
It has a range of deployment options that can be used to fetch the exact same data.
Users are able to perform sophisticated analytics because it supports OLAP (online analysis processing).
The application is composed of numerous queries that provide flexibility to users.
Teradata offers a variety in services (full) related to the storage of data.

Features of Teradata

Teradata database comes with the following features:

Structured Query Language (SQL): Teradata offers an extension for SQL that communicates with data.
Linear scalability A: The Teradata system is able to be scaled up linearly to increase amount of data nodes. The increased number of nodes boosts overall system performance.
Unlimited parallelism: This feature enables massive tasks to be split into small tasks. The task can be run in a parallel manner.
Automated distribution: The disks’ distribution of data does not require manual intervention (it is automatic).
Optimizer for mature users: Teradata provides an enhanced optimizer that supports many joins for one query.
The total cost of ownership (TCO) The system has the lowest TCO. This is due to the ease of setup, administration and maintenance.
Robust Utilities: It consists of powerful utilities like Multiload, FastExport, TPT, and FastLoad. These utilities allow users to transfer or import data (from or to the Teradata data system).
Connectivity Teradata System allows connection with other systems like mainframes and network-attached systems.
Load and unload utilities: It includes load utilities which can be used to load details into Teradata system. Additionally, it includes unload utilities that carry data out of the system.
Shared nothing architecture The database is the shared-nothing model, which means that disks, Teradata nodes and AMPs (Access Module Processors) are all independent. This is not able to allow sharing of resources, which enhances performance for a specific task.

The architecture of Teradata

The structure of Teradata client tool is founded on the concept of MPP (massively simultaneous processing). It is split into two parts: storage architecture and retrieval architecture. The whole architecture is made up of four main components: the an engine for passing, the AMPs, BYNET and disks. The two first components comprise the storage architecture, while the remaining two are the retrieval architecture.

Storage architecture

This is the way to go when the client makes the storage query.

Parsing engine

The following are the specific role of a parsing engines in the storage system:

It processes its queries (SQL) generated by the clients.
It analyzes the queries to establish whether there are syntax mistakes.
It checks the availability of objects that are used in SQL.
It creates the execution plans that are used for the queries. It then sends the queries to BYNET.
It takes the results that result from an SQL query using the AMPs and forwards it to the user.

Access Module Processor (AMP)

This is a virtual processor that is linked to BYNET. Each AMP consists of a specific disk that allows it be able to read as well as write.

An AMP accomplishes the following duties:

It is based on a portion of an table.
It examines the records stored on disks.
It plays a role in the generation of the final outcome. These include aggregation, joining, and sorting.
It manages lock and space management.

Retrieval architecture

BYNET

This component connects the parsing engine with the Access Module Processor. It’s a layer for transferring messages. BYNETS are available in two major versions: BYNET 0, and BYNET 1. In the event that one ByNETs fails to work properly, the other one could be used to replace it. Both forms can be employed for data storage if the volume utilized is massive.

Disk

It’s a place to store data for AMPs. They are also known as Vdisks or Virtual disks.

How Teradata functions

Teradata operates through the four components described above. The system’s operation is dependent on the kind of query being made by the user. If the client wishes to insert records then the storage architecture is utilized. In this scenario the parsing engine will be able to receive the storage query (insert records) to process.

The parsing machine consists of four main elements that work systematically on the query: the parser and session handlers, optimizer and dispatcher.

The method of operation in the parsing engine may be described in the following manner:

Parser: This evaluates the syntax, and then forwards the query to the following item (system handler).
The system handler checks whether the user has the right logging credentials to execute the query.
Optimizer: This determines the most efficient plan for the execution of an SQL query.
Dispatcher: This forwards your query directly to the Access Modul Processor.

The table rows are distributed across all AMPs that are available. The AMPs are able to lock the table and then execute the program created from the engine parser. When the execution is complete it is then the AMPs will complete the process and store the results on their own disks.

If the client needs to retrieve data, the retrieval architecture is used. The relevant query is transmitted to the parsing engine. The parsing engine generates an request and then sends it to BYNET. BYNET will forward the request to the AMPs. The AMPs will then conduct a parallel search and locate the desired records. These will be forwarded to the parsing engine via BYNET. The parsing machine will forward the information on to the user.
