Oracle (the software) isn't a database, though. It is a database management system. It seems highly unlikely that it kept all the data in one place. Different workloads generally need different database structures. And Amazon circa 2008 was complex enough that it no doubt had a gamut of different workload needs, even if that was all managed under one management system. Really, as it pertains to this, it is a question of "where do I want to move the complexity to?", not "can I eliminate it?"
