PostgreSQL is an effective open-source database administration system, which has been growing in level of popularity lately as a result of its stability and reliability. It includes many innovative features and it can be used to save any sort of information. PostgreSQL could be interfaced with many different programming languages, like PHP, Python, Perl, Java, C++, Ruby, and so forth. In addition, it could be used for scalable applications since a single field inside a PostgreSQL database may be up to 1 GB, a table - up to 32 Gigabytes, while the database as a whole doesn't have a limit for its total size. PostgreSQL also works faster than other SQL administration systems when complex operations are executed. A lot of big corporations and organizations have already migrated to PostgreSQL for their Internet sites or products - Apple, Cisco, the US State Department, the University of California, Berkeley, and others.
