Summary: Oracle/Microsoft domination in databases is eroding as new players that consider themselves to be “open-source” gain traction
Google is phasing out and moving out of MySQL [1,2], dealing a blow to Oracle  after Oracle sued Google (over Android). Oracle has had a lot to fear because of Free software. Oracle essentially shares Microsoft’s pain. PostgreSQL, in the mean time, has a new release  and MongoDB , one of the NoSQL databases [6,7], shows promise. These new trends in the databases market sure work in favour of Free/open source software because the main gainers here are — for the most part — at least partly Free software. Companies like Microsoft and Oracle are poised to lose and Red Hat et al. will gain. █

Linux distributors have been moving from Oracle’s MySQL to its popular fork, MariaDB – and now Google is also moving to MariaDB.
‘They’re moving it all,’ says MariaDB Foundation headman
In 2010, when Oracle took control of Sun Microsystems, they became the minders of a host of open source projects that included OpenSolaris, Java, MySQL and OpenOffice. They’ve since quit developing OpenSolaris, although the project lives on as the forked OpenIndiana project; OpenOffice now belongs to Apache; Java, especially on the browser side, has been beset by a long list of security issues and MySQL has been forked by its creator into MariaDB.
MySQL, MariaDB and PostgreSQL are three major open source databases which dominate the market. According to Jelastic PostgreSQL is neck to neck with MySQL fork MariaDB and MongoDB.
Forget about joins and SQL and try NoSQL databases – specifically MongoDB, the leading example
NoSQL isn’t just for big servers anymore, as Couchbase Lite brings open-source database technology to the mobile form factor.
Open-source NoSQL database vendor Couchbase is growing its portfolio from the server to mobile devices with its new Couchbase Lite initiative. Couchbase is also releasing a new server version as well, providing improved security and administration capabilities.
Couchbase develops and sells an open-source NoSQL database that to date has been a server-deployed product. The Couchbase Lite effort changes that, providing developers with a native small footprint database that can run on either Apple iOS or Google Android mobile operating systems.
Database startup Couchbase has developed what it believes is the first NoSQL database for mobile devices, but why would anyone want such a thing?
