* Last I checked, Oracle allowed you to use Oracle RDBMS free for "prototype development" but once you were actually generating revenue from that you are supposed to buy the necessary licenses, even for continued development or support purposes.
Hm... I vaguely remember (but it was a really, really long time ago) you could use Oracle for as long as you wanted as long as you didn't process your own or your customers' business data.
Oracle doesn't go after startups. Or even companies like Facebook or Dropbox etc.
It goes after: government agencies, banks, insurance companies, multi-nationals, huge retail chains, logistics, payroll, and such. And it does a killing at it.
Web style big-data are not Oracle's domain.
And it's not like those startup people will afterwards (when they "grow up") go work in the enterprise and use Mongo and MariaDB there. It's just different kind of problem domains altogether.
As per my comment above, Oracle doesn't care about those startups, whether they become the "software giants of tomorrow" or not.
They sell to government agencies, logistics, payroll, multi-nationals, banks, finance, insurance companies, etc.
Those sectors do not overlap with the startups using MariaDB, Mongo, or what have you. Totally different problem domains and people.
In particular, this is banking (an extremely heavily controlled industry), and telecom (regulation here is mainly just to keep out competition, not as much to control).
You're going to see more open-source based solutions on the periphery, but core systems are a whole different thing.
I agree that it's sort of narrow-minded, in that there are reasons to use Oracle and IBM outside of the industries and use cases I singled out. I'm not sure why it's incorrect, though (feel free to enlighten me).
where the license cost makes sense. I see a lot of big Oracle HA configurations where downtime or data-loss is unacceptable (and very pricey), where management wouldn't risk their careers choosing something that a start-up would consider.
Is it really true that Oracle's products are superior if you're going for "no downtime, no data loss, cost not so important"? I don't have any experience in that arena. But I would expect an open source options to be competitive.
If the Oracle products are really worth it, what explains that?
Is it that you can get Oracle people on the phone at any hour whose sole job is to fix it, and there isn't similar open source support? (If so, why isn't there? Red Hat plays this role for Linux.)
Is it that Oracle software is just too complicated and well-done and smart to be replicated in the open source world? "In theory," that should not be the case, but maybe the database equivalents of Linus Torvalds always end up just working for Oracle, or something.
One. The products are well understood. Not just from a technical perspective but operationally as well. Generally enterprise companies have dedicated DBAs either in house or on call. Two. There are unlimited support options. Three. Almost all enterprise software works with Oracle and many are only supported for use on Oracle.
You ARE seeing open source adoption in particular MongoDB, Cassandra in specific areas of the business. But they are almost exclusively "non-core business".
Pretty much - Oracle's clustering/replication options are still considerably superior to even a 'real' open source RDBMS like Postgres (as well as providing better performance). MySQL, by contrast, is missing so many important capabilities (transactional DDL, check constraints, window functions, joins other than nested loop) that it's not (imo) especially worth considering.
If you look outside the realm of open-source RDBMSs to NoSQL, you tend to find that they'll be missing some critical feature for reliable database operations, like transactionality, or simply won't be that feature rich (i.e. key-value stores). This is not to say that NoSQL stores don't have a place, just that they tend to be designed around web use cases where trading off consistency can be worth it.
I'm not meaning to hate on open source DBs here - I think Postgres is fantastic and easily sufficient for most use cases. Technologically Oracle/DB2 are still better products, though.
When it comes to the people in charge of the money, it seems Oracle's not doing too bad a job.
