PostgreSQL is an excellent open-source database administration system, that has been growing in global recognition lately due to its stability and reliability. It provides numerous advanced functions and it could be used to store any sort of information. PostgreSQL could be interfaced with many different programming languages, such as PHP, Python, Perl, Java, C++, Ruby, and so on. In addition, it may be used for scalable apps since a single field in a PostgreSQL database may be up to 1 Gigabyte, a table - up to 32 Gigabytes, while the database in general doesn't have a limit for its total size. PostgreSQL also performs swifter than other SQL control systems when sophisticated operations are performed. Lots of huge businesses and organizations have already moved to PostgreSQL for their sites or products - Apple, Cisco, the US State Department, the University of California, Berkeley, and others.
