be prudent to go with that option for DB2 (relational) users?
Unlike other warehouse systems, Teradata is based on the relational model and the use of MPP technology gives Teradata a huge edge in the real-time world.
With virtually every other warehouse system you load data into it by batch processing extract, transform and load (ETL) routines — typically overnight — and then there is a pause, often of several hours, while the data is indexed, aggregated and generally readied for querying. With Teradata's Enterprise Data Warehouse (EDW) you can load in data much more frequently and it is available for querying immediately.
So, if your goal is data warehousing with real-time analytics, check out Teradata. If you need a fast, MPP transactional database, check out DB2.
