The long way of #JSON in #Oracle, from 12.1.0.2 until today. Now starting with 23ai and still 15 minutes left. Not bad!
You can do it!

The same topic, the same @danischnider.bsky.social, but something has changed, the stage dimension perhaps? Note: stage dimension is not a new term in data warehousing, Dani is speaking about 😃

Excited to speak at #UKOUGDiscover24!

Join my session on 2 December at 16:00. See you there!
