Moving to TeraData was what caused me to leave my previous position.

The idea that Oracle can't handle Terabytes of data is ludicrous.

Pricing? Plan to spend 5x as much on a Teradata solution.

Star schemas? Take a look at how Teradata does joins on a Star schema. It's ridiculous. 7-11 has a huge multi-terabyte DW with tables that have Billions of rows. They can do DW queries against these stars and return results in 7 minutes. ( old data, probably faster now. )

Teradata was designed as a high speed OLTP database. I doubt that they even have much of an advantage in that arena anymore; I think of them as a legacy app that is fighting for survival.

Marketability? Goto and lookup all the jobs for available for Teradata, then look up the same thing for Oracle.

Last time I checked it was 69 nationwide for Teradata, 6900 for Oracle.

Do the math.
