soner2 asked: Hi there, I wonder what do you think about MongoDB and Mongoid? I'm confused to use them or not. I'm between PostgreSQL and MongoDB... Well, so a relational database and a document-oriented database. Thanks for your reply.
Stick with what you know unless you have a good reason for using something else. I have a video on nosql that may or may not help http://www.youtube.com/watch?v=oL-A4JYwgH4
