PostgreSQL pronounced “Post Gress Cue Ell” and often shortened to “Postgres”, is a free and open source object-relational database management system (ORDBMS) that runs on all major operating systems: Linux, UNIX, Mac OS X, and Windows.
PostgreSQL: The Strength of Organized Data
Anyone familiar with the basic order of Excel or Numbers can immediately recognize and engage with the same simple but effective structure of tables and rows in PostgreSQL. PostgreSQL is known for the security of its data storage and for its ease of migration through strict adherence to standards compliance; you can rest assured that your data will be safely and reliably stored, as well as easily migrated should the need arise.
Postgres has the same speed, compatibility, SQL, and features of top commercial databases while remaining free and open source. PostgreSQL is highly scalable in terms of both the volume of concurrent users it is able to accommodate and the sheer quantity of data it can manage at once (some databases managing in excess of four terabytes).
PostgreSQL Is Advanced Enough for These Companies
Hundreds of companies and organizations use Postgres to build their web sites, products, solutions, and tools. Because Postgres is the most advanced open source SQL database system around, it is utilized by many different commercial and nonprofit entities ranging across a variety of fields—e-commerce, education, finance, government, media, open source projects, retail, technology, telecom, and more.
It is trusted by Apple, Etsy, Fujitsu, Skype, Whitepages.com, IMDB.com, Debian, LAMP, Sourceforge, and the U.S. State Department, to name just a few. To read a much larger (but by no means exhaustive) list of their users, click here.
