PostgreSQL is a feature-rich object-relational database control system, that's famous for being among the most secure and dependable systems available on the market. It's cross-platform (Linux, UNIX, Windows, FreeBSD) and cross-language (PHP, Ruby, Java, Perl, Python), that makes it universal and a lot of organizations and corporations are already working with it for their products or their own Internet sites - just a few examples are Apple, the US Department of Labor, and Skype. The system is open-source and highly customizable, not mentioning that it is far better than other management systems with regards to managing sophisticated operations. In addition, the fact that a single table could be up to 32 Gigabytes in size, while the database size is unlimited, makes PostgreSQL an outstanding solution for scalable applications.
