Is Oracle database widely used in the USA?

And what you think about the Oracle database? Now, when I look in the available positions in Turkey here is what I see. Oracle, 503 positions. PostgreSQL, 17 positions. MySQL, 158 positions. SQL Server, 372 positions. MariaDB, 0 position. NoSQL, 18 positions. Redis, 9 positions. Some people say that in West USA no one uses Oracle.

  • Oracle is used widely by large organizations, such as governments and corporations. Same as IBM's DB/2.

    It is not used widely by San Francisco start-ups though. So you'll see more blog articles about PostgreSQL or MySQL as more start-up people blog than government people.

  • Oracle is used extremely widely in the US. For example, many US government agencies use it. Many companies use it.

    I suspect its use has not grown as rapidly as other technologies.
