CUBRID is a great free and open source option optimized specifically for web applications, useful when complex web services process large amounts of data and generate huge concurrent requests. This solution is implemented in C.

FIREBIRD

Download

This relational database has been used in production systems (under a variety of names) since 1981 and features many ANSI SQL standards. Firebird is capable of running on Linux, Windows, and various Unix platforms.

MariaDB

Made by the original developers of MySQL, MariaDB is used by tech giants like Wikipedia, Facebook, and even Google. MariaDB is a database server that offers drop-in replacement functionality for MySQL. Security is a top concern and priority for MariaDB developers, and in each solution release, the developers also merge in all of MySQL’s security patches and enhance them if need be.

MongoDB

Download

MongoDB was founded in 2007 and is known as the “database for giant ideas.” Developed by the people behind DoubleClick, ShopWiki, and Gilt Groupe, MongoDB is also backed by popular investors such as Fidelity Investments, The Goldman Sachs Group, Inc., and Intel Capital. Since its inception, MongoDB has been downloaded 15 million times and is supported by more than 1,000 partners. These partners are dedicated to this free and open source solution’s belief that coding and databases should be simple and natural.

MySQL

Download

MySQL has been around since 1995 and is now owned by Oracle. While open source, there are also several paid editions available that offer additional features, like cluster geo-replication and automatic scaling. Because MySQL is an industry standard, it’s also compatible with just about every operating system and written in both C and C++. This solution is a great option for international users since the server can provide error messages to clients in multiple languages, encompassing support for several different character sets.

PostgreSQL

Download

With more than 15 years of active development, PostgreSQL is another stellar open source option, running on all major operating systems, including Linux, UNIX (AIX, BSD, HP-UX, SGI IRIX, Mac OS X, Solaris, Tru64), and Windows. PostgreSQL is also fully ACID (Atomicity, Consistency, Isolation, Durability) compliant.

SQLite

Download

Self-proclaimed as the most widely deployed database in the world, SQLite began in 2000 and has been used by notable companies like Apple, Facebook, Microsoft, and Google. Each release is carefully tested to ensure reliability. Even if there are bugs, the developers of SQLite are honest about potential shortcomings by providing bug lists and chronologies of code changes for every release.
