Postgre SQL or simply called Postgres is a type of object-relational database server with open source user license. Postgres database server has evolved through more than 15 years of development and maintenance and is considered one of the most reliable databases with extensive focus on data reliability and correctness. Postgres supports all the modern features of any database system and can be installed and run on variety of platforms including Linux, Windows, and all the versions of UNIX. Postgres also has integration support for various programming languages Python, Perl, .NET Languages, C++, Java, TCL, ruby and other similar platforms.
Michael Stonebraker, a professor at the University of California at Berkley is credited with being the inventor of Postgre SQL or Postgres. Postgres is a successor of Ingres which was another database system developed between 1977 to 1985. Stonebraker decided to build a more advanced version of Ingres which is more robust and has improved performance. It took Stonebraker and his colleagues at UCB, eight years (1986-1994) to completely develop the Postgres database system.
Andrew Yu and Jolly Chen, two Ph.D. students at the UCB lab working under Stonebraker further improved the database server by replacing the POSTQUEL query language with more popular and widely used SQL. This improved version was named as Postgres95. In the year 1996, Postgres95 entered the software industry for the first time and become one of the most robust and widely used open source database servers.
There are several reasons why you should use Postgres for your database development purposes. Some of them have been highlighted below.
The first major benefit of using Postgres is that it is open source and you can customize it according to your requirements whenever you want. This customization capability is immensely useful in large scale application development.
Postgres has been in the market for more than 15 years and its developer community has immensely grown in this time. Large developer community means good support and help in solving database related problems.
Postgres is extremely cost effective and not much user training is required to learn how to use and program for this database. Also, maintenance and tuning requirements of Postgres database are negligible as compared to other database systems.
Good thing about Postgres is that it is portable with almost all the major platforms and programming languages. This database is ideal for applications targeting multiple platforms.
Postgres database server does not require extensive command line configurations. Several tools and GUI interfaces have been developed which can aid you in easy installation and management of the database server.
Postgres is worldwide recognized as being the most reliable and stable database. The chances of database crashing are minimal and even if database crashes there are ways and features which allow you to restore and recover the data.
Overall, Postgres is highly recommended database particularly for those organizations that prefer to use freeware and open source software. It is robust, fast and highly stable database.
