MySQL and MongoDB represent two sides of an argument that has been raging recently concerning data storage – the tried and tested relational database vs. non-relational or NoSQL database. They are both open-source products distributed under a version of the GNU GPL, and both are also available as commercial versions offering many more features and corporate support.
MySQL and PostgreSQL are two of the most popular open-source RDMS (Relation Database Management System) programs on the market. They have competed favorably with commercial closed-source database programs for many years. Each has developed a reputation for specific strengths and weaknesses. MySQL is perceived to be much quicker but offers fewer features. PostgreSQL is believed to have a deeper feature set. Some programmers think of PostgreSQL as being similar to Oracle, and it is often favored by those who know Oracle products.

But reality tells a different story.
