We have used Oracle and Microsoft SQL, but we haven't had much success. We found that Oracle was not as scalable and we were having some performance bottlenecks. Also, from a licensing perspective, Greenplum was a better choice. For all of these reasons, we have chosen to invest heavily in Greenplum.

We did a comparison among some databases, one of them Greenplum. We assessed features, did a comparison in terms of the price, then we chose Greenplum. And we've retained it. We've found it's a good product, to date.

Oracle Exadata was part of the comparison, as was IBM Netazza. In terms of quality and the price, compared to the other products, we chose Greenplum. Also, to be honest, at that time we got a good offer: Use it for the first year with a minimal price. Then they opened a support contract with us, later. That was one of the advantages.

We also looked at Teradata.

We evaluated other solutions. Not sure of the reasons why this product was chosen.

Prior to choosing this solution, we evaluated MySQL and PostgreSQL.

We evaluated Oracle technology that we used before.
