PostgreSQL is a powerful open-source database control system, which has been growing in level of popularity lately on account of its stability and dependability. It provides numerous sophisticated functions and it can be used to save any type of information. PostgreSQL could be interfaced with numerous programming languages, such as PHP, Python, Perl, Java, C++, Ruby, and many others. Also, it can be used for scalable applications due to the fact that a single field in a PostgreSQL database could be up to 1 GB, a table - up to 32 GB, while the database altogether doesn't have a limit for its total size. PostgreSQL also operates swifter than other SQL management systems when complex operations are carried out. A lot of huge 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.
