You can tell a lot about a developer by their preferred database.
* Mongo: I like things easy, even if easy is dangerous. I probably write Javascript exclusively
* MySQL: I don't like to rock the boat, and MySQL is available everywhere
* PostgreSQL: I'm not afraid of the command line
* H2: My company can't afford a database admin, so I embedded the database in our application (I have actually done this)
* SQLite: I'm either using SQLite as my app's file format, writing a smartphone app, or about to realize the difference between load-in-test and load-in-production
* RabbitMQ: I don't know what a database is
* Redis: I got tired of optimizing SQL queries
* Oracle: I'm being paid to sell you Oracle
