Daniel Fowler9 said:Who actually cares about database storage size? I guess all that matters is how many SQL Server or Oracle licenses were sold, even if they're just running databases that are two kilobytes big. It’s all about the raw numbers—how many of one versus the other—and clearly Microsoft is winning the database game too (just look at page 65 of the report!). You should probably do some reading.
This is just another comment that proves you don't really grasp the IT market, how these technologies are actually used, or how to read statistics. Where is the logic in that, especially since you claim to be a mathematician? But then again, I suppose there are always people who miss the point.
First off, people ask about system counts, not total investment or anything else.
Enterprise licenses are billed based on capacity, CPU count, and so on. This isn't the consumer desktop market.
It's the same when someone asks if they use Windows as a server; you never know what kind of server we're talking about. Most people have Windows servers because they use Windows for desktops and non-critical edge applications. That's a far cry from claiming Microsoft dominates the high-end server segment.
The top tier is still dominated by Unix, and that isn't changing anytime soon.
Furthermore, this statistic is based on a sample of just over 1,600 companies of all sizes. That doesn't represent much in any specific segment. Besides, this data is just for the US, which is much more favorable toward Microsoft than the rest of the world (just remember the European Union is still tied up in legal battles with Microsoft, and there's a good chance the fines will be massive).
Not to mention, Linux is being integrated into government agencies more and more, pushing back against Microsoft (and Microsoft makes its money on Office, anyway).
That's just a few thoughts. Next time, maybe think before jumping into these discussions. As the saying goes, "there are lies, bigger lies, the biggest lies, and then there's statistics."
