Notes

Oracle9i can scale tens of thousands of concurrent users, support up to 512 petabytes of data (a petabyte is 1,000 terabytes), and can handle any type of data, including text, spatial, image, sound, video, and time series as well as traditional structured data.
Prior to Oracle9i, user defined functions can be only single-row functions. Starting with Oracle9i, user-defined functions can also be defined as aggregate functions.
