Larry bought Oracle off some real programmers about 20 years ago and has progressively marketed it to suckers in government and industry as a big end database. Whereas it is true it can handle pretty big datasets, it is nearly impossible to use after Larry's shammers have piled crap onto the API in such volume no man in his lifetime could ever hope to learn how to make an SQL call without years of study. Compare with ADO in Windows, takes five seconds. You can see why they have nowhere to go but down.
All across the Western world you have these people who are billionaires "just because." They never did anything for anybody, added anything innovative to the world or contributed to total human progress. They just knit a web and sit there waiting for rubes to wander in and get tangled. Then they suck them dry and toss their wrinkled husks onto a heap nearby.
The poor saps who got on the Oracle bandwagon ten years ago now face astronomical costs for migration if they want to get off this shortbus. Some of them are apparently deciding that rather than wait any longer they need to dump this 90's circa technology before Larry's team of idiots add any more to the API.
