PostgreSQL is an advanced relational database management system, which can be used on many platforms (UNIX, Linux, FreeBSD, OpenSolaris, Windows) and with many scripting languages (Perl, PHP, Python, Java, Ruby). Since it is open-source, it may be easily modified to match the needs of any developer who uses it. PostgreSQL is also among the most dependable and stable database systems, with superior functionality in handling sophisticated operations compared to similar systems. It is suitable for large-scale applications due to the fact that a single PostgreSQL database doesn't have a limit for the size, while an individual table may be up to 32 Gigabytes. It isn't a surprise that a number of business, academic and governmental organizations are already employing PostgreSQL - Skype, the University of California, Berkeley and the US Department of Labor being just a couple of examples.
