Wow – one of our reference projects went into the Yahoo Finance webpages. Carol Tagliaferri (my direct manager) worked with CSX, one of the largest US based railway companies, over a longer period together with the RAT team, and helped CSX to successfully upgrade and migrate their database landscape to Oracle Database 11.2.
Plus: We did present about CSX at Oracle Open World 2012 as this project is a perfect showcase for:
(a) an Upgrade project with many databases
(b) over a longer period of time
(c) using Real Application Testing decreasing the testing effort by factors!
