TERADATA came into existence with a goal and dream in mind, businesses that wants to build huge data wareshouses don't have to compromise because their database is unable to meet the challenges and requirements of constant change. It has the ability to quickly respond to changing conditions and is more flexible than any RDBMS. It is designed to perform parallel processing and has the capability to be flexible linearly and accommodate terabytes of data.
In short when other database vendors designed their databases around OLTP (Online Transaction Processing) and stopped thinking further, But that's where TERADATA started thinking, they came up with an idea to design a database for OLAP (Online Analytical Processing) or DSS (Decision Support Systems).
Teradata Architecture is simple and complex in itself. It is simple because the user doesn't have to worry much and complex because the RDBMS has its own complex algorithms and intelligence that knows the easiest and fastest way to retrieve data. It also has its own way of storing the data. Teradata based on the fundamentals of mathematical set theory. It is the database that loads data in parallel, backups data in parallel and process data in parallel. It is a story of parallel processing.
In my next post I'll give an overview and Architecture of the TERDATA so that it will be a jump start for all the nacent users.
