Yes, while a lot of the buzz is for the likes of MongoDB and other “cool” NoSQL platforms, the top two database distributions—by far—are owned by Oracle. And they are both SQL-based.

MySQL is the second most popular database in use, according the DB-Engines Ranking, and is a key element of the LAMP — Linux, Apache HTTP Server, MySQL, PHP — open-source web development stack.

For the second year running, DB-Engines ranked Oracle at the top, with MySQL and Microsoft SQL Server following extremely closely in second and third position.

Oracle has responded by offering its own noSQL database, with mixed success. Oracle’s flagship database is by far the most popular database out there, but MongoDB is by far the most popular noSQL.
