Twitter DataBase Query

[More Info]

Would appreciate if someone could tell me what database program is used by sites like Twitter, Facebook etc.

Has anyone out there worked on similar sites of same magnitude?

Thanks in advance.

Could be a range of things. I doubt they use a free database such as MySQL, but they might of started that way. Many large organization use Oracle which traditionally runs well even with millions of rows and tables. Some use Microsoft SQL Server. There are other commercial databases out there was well. I know MySQL has one but I have no knowledge of it.

I think Twitter uses MySQL.
