PostgreSQL is an effective open-source database administration system, that has been growing in level of popularity lately on account of its stability and dependability. It provides many advanced functions and it could be used to save any sort of information. PostgreSQL may be interfaced with many programming languages, like PHP, Python, Perl, Java, C++, Ruby, and many others. Furthermore, it could be used for scalable applications since a single field in a PostgreSQL database could be up to 1 GB, a table - up to 32 Gigabytes, while the database as a whole does not have a limit for its total size. PostgreSQL also functions swifter than other SQL management systems when sophisticated operations are carried out. A lot of big corporations and organizations have already migrated to PostgreSQL for their web sites or products - Apple, Cisco, the US State Department, the University of California, Berkeley, and others.
