seems Mr Ammar Afzal is a Data Base expert, and has Oracle 9i certification......can't say exactly what the problems he was able to unravel......if you read the Urdu version, it states US banks were experiencing data base problems that he was able correct.
**Oracle 9i is not the tops in Oracle........I think it goes all the way up 11i............
That is why I wondered what was it that a 9i could solve and not the 10i's or 11i's.....**
Basic & Fundamental functionality & layout/processing engine is same for all the versions with some minor addition/changes, "i" represent for internet, i took the certification exam in my school years like 7 years ago.
