"One of the biggest challenges in the new sales management system was to process order inputs from distributors and dealers all over the world with responses higher than those of older generic aircraft. Therefore, we chose several high-speed database products and evaluated them with thirty items of check lists including performance, migration, operation and cost, Oracle Exadata came up as the most promising candidate. Ultimately, from the fact that usual SQL statements can be used as they are during development, that the database tuning after the test and the production run is almost unnecessary, and the prospect of achieving the target response with the verification result on the actual machine , I concluded that there is no choice other than Oracle Exadata."
