PostgreSQL is a powerful open-source database control system, which has been growing in popularity lately because of its stability and reliability. It includes plenty of advanced features and it could be used to keep any type of info. PostgreSQL can be interfaced with many programming languages, like PHP, Python, Perl, Java, C++, Ruby, and so forth. Also, it can be used for scalable apps because a single field inside a PostgreSQL database can be up to 1 Gigabyte, 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 complicated operations are executed. A lot of major corporations and organizations have already moved to PostgreSQL for their sites or products - Apple, Cisco, the US State Department, the University of California, Berkeley, and more.
