If you are like me, you probably have wondered which is better- MySQL or PostgreSQL. Well both have their strengths and weaknesses. Your choice of either will depend on your task at hand.
“MySQL vs PostgreSQL is a decision many must make when approaching open-source relational databases management systems. Both are time-proven solutions that compete strongly with proprietary database software. MySQL has long been assumed to be the faster but less full-featured of the two database systems, while PostgreSQL was assumed to be a more densely featured database system often described as an open-source version of Oracle.
“MySQL has been popular among various software projects because of its speed and ease of use, while PostgreSQL has had a close following from developers who come from an Oracle or SQL Server background.”
The full comparison of the two database management systems can be found on this wiki page. So if you are undecided about which of the two to use, then you surely should find some insight in the above linked comparison page.
