• As I think, this is depend on cost and familirity. I read the page what you have mentioned but can't agree to all like partitioning, triggers, external file accessing. Even bitmap indexing is also available in SQL 64-bit version. Some parts are unknown to me as I do not have much experience in Oracle. It is better to read this page by someone who has good knowledge on both sides and let us know.
