The Growing Prominence Of Teradata Among Data Enthusiasts
Recommended by 29 users
Teradata, the large scale relational database management system, today holds the place of the world’s largest commercial database program. If you have dealt with any form of Big Data in your career, it is unlikely that the term ‘Teradata’ has never surfaced. The ability to store data up to terabytes in size has made this platform the biggest and the most sought after database management system in the world today.
The Basics of Teradata
The Teradata database management system uses the concept of parallel processing to move information to a data warehouse where it can be stored, recalled and analyzed as per the requirements of multiple clients simultaneously. Most database management systems can only be scaled in one field at a time, and this often causes other areas of data to fail. The parallel processing relational Teradata program is fully scalable and offers load distribution among multiple users. One other notable feature about this data warehousing system is that it employs a ‘shared nothing’ architecture. This means that each node of the server has an independent memory and power processing unit making it possible to add more servers and consequently more data as required without compromising the speed and the capability of the overall program.
Why Has Teradata Become So Popular?
Complete scalability along with parallel efficiency is causing data enthusiasts to slowly but surely migrate to Teradata warehousing systems. To begin with, Teradata supports more data at once than all its competitors combined. That is some massive capacity for a single data warehousing system which is making it a popular choice for large organizations.
Kilobytes, gigabytes and terabytes have become terms of common usage, but Teradata introduces us to the ‘petabyte’. A petabyte is the measure of storage capacity of approximately one thousand terabytes. The Teradata systems can scale from 100 gigabytes to more than 100 petabytes at one time on a single system without compromising the functioning or performance of the database management tool. This is an entirely new ballgame, one that all data enthusiasts would love to play.
The multiple nodes and joins, independent server memory and processing systems enable the Teradata software to run multiple complex queries at the same time. The parallel processing system also ensures that the database management tool can handle several concurrent users while the automatic distribution of data eliminates complications and the need for continual reorganizations of data.
The Teradata database also comes with a parallel “optimizer”. In most database management systems, it is necessary to tune a query repeatedly to ensure that favourable results are obtained. This can mean a lot of trial and error before you obtain the desired results without any error. The parallel-aware optimizer however, fine tunes the query automatically to ensure that it runs without a glitch. This means a lot less wasted time and effort, and faster results.
The Teradata system has an inbuilt fault tolerance mechanism. Unlike most systems which have a single point failure causing the entire system to crash in the event of one irregularity, Teradata comes with multiple nodes and joins which allow the program to retain overall functionality in the event of a problem. Thus, the inbuilt fault tolerance mechanism allows for high availability of data without loss of information.
The Future of Teradata
Experts believe that Big Data, Analytics and Data Warehousing are here to stay. As of today, data is one of the most valuable aspects of business. With the number of connected devices increasing every day, there is a need for focused analytics systems which will enable the transmission, analysis and mining of data at rapid speeds and at high performance levels.
With the internet of things slowly but surely becoming a tangible reality, it is becoming increasingly important to make information more accessible and this is where large scale data warehousing systems come into play.
The Teradata database management system can be applied in a number of areas. It can be used for enterprise or active data warehousing and even for customer relationship management in large scale organizations and MNCs that cater to a wide variety of clients at the same time.
