PostgreSQL is a feature-rich object-relational database administration system, that is recognized for being among the most stable and dependable systems available. It is cross-platform (Linux, UNIX, Windows, FreeBSD) and cross-language (PHP, Ruby, Java, Perl, Python), which makes it universal and many organizations and corporations are already employing it for their products or their own web sites - just a couple of examples are Apple, the US Department of Labor, IMDB.com and Skype. The system is open-source and extremely customizable, not mentioning that it is superior to other administration systems with regards to managing complex operations. In addition, the fact that a particular table could be up to 32 Gigabytes in size, while the database size is unlimited, makes PostgreSQL an incredible pick for scalable applications.
