Netezza and Oracle

Virgin Media says,

"Before Netezza we could never be sure how long a query would take. Compared with the old Oracle-based system, the new one is, incredibly, 252 times faster on average."

Netezza and Oracle

Exadata is primitive, slow, expensive, closed, power-hungry, cannot handle advanced analytics and requires significant management overhead.

But other than that, it’s not a bad start for Oracle!

For over five years, Oracle users have been sharing with Netezza their concerns about the performance of Oracle as either an enterprise data warehouse or for specific analytic applications. And as data volumes grow, analytics become more complex, users demand faster response and cost reduction initiatives become rampant, Oracle users have simply been unable to keep up. So much so, in fact that over 100 of these users turned to Netezza and our data warehouse appliances for a solution.

The Exadata systems are Oracle’s response to Netezza. Like Netezza did some seven years before, Oracle has realized that an architecture where SQL processing is carried out close to the disk yields all sorts of performance gains. Data not required in a query is filtered out at the source and is prevented from causing a bottleneck between storage and the database where the complex processing is carried out. And just like Netezza did, Oracle has also recognized the benefits of massively parallel processing.

But it’s here that the similarities end and fact can be confused with fiction. With Exadata, what are you really getting? Users will find that the Oracle world hasn’t changed that much in the last five years.
