- Parsing Engine the boss/ mind behind the whole Teradata architecture, it takes SQL from user, comes up with a plan over one of two byNets (byNet0 & byNet1) and the AMPs get its simultaneously, they do their portion of work and return it to the parsing engine over the byNet
See, how beautifully the whole table is distributed over multiple AMPs.
TeraData systems can add AMPs for Linear Scalability for large data to define the key feature of any datawarehouse. This process of parallel AMPs give more processing power to the indexing techniques (Unique Primary Index & Non Unique Primary Index) by following beautiful Teradata architecture.
So, all in all its a powerful tool to handle large amount of data in fast and furious amount of time.
