I have only worked for a year with an oracle db and generally are not a db guy (more image processing, physics simulation, hardware control etc), but what i gathered back then was oracle can be a beast in db performance. Features ... errr, dunno but in my eyes they are all about being fast at relational queries.
A) how do you brag about that other than comparing to how others do on that very same field
B) i can see them actually doing extremely well in /that/ field also in the cloud, but hypy things like big data seems to be about unstructured data.
dunno why; the things i would guess the most valuable for business intelligence, where probably the money lies, /should/ be structured to have value. IOW, if oracle manages to offer relevant help at BI also with "AI" (tho i still shudder at the thought of "pretrained" AI models to use in BI) they should be set up good to help others make money (in contrast to sink money into hype).
Disclaimer of course i'm no expert on any of this, just seeing +/- from the sidelines what some few companies in one very specific field (medtech) are interested in/struggle with, apart from the -inherent to that field- "how do we remain or even get compliant to the gazillon and ever changing regulations".
