Tipagem
Por não ser necessária a declaração do tipo, muitos pensam que a linguagem Ruby é fracamente tipada
e com isso o tipo não importaria para o interpretador.
No Ruby os tipos são importantes sim para a linguagem, tornando-a fortemente tipada, além disso,
o Ruby também é implicitamente e dinamicamente tipada, implicitamente tipada pois os tipos são inferidos pelo interpretador,
não precisam ser declarados e dinamicamente tipada porque o Ruby permite que o tipo da variável possa ser alterado
durante a execução do programa

why mongodb, and really why not!!

That's not to say that MongoDB isn't high performance, but its place probably isn't serving blogs.

NoSQL definitely has its uses. But it's definitely not the answer for everything.
The main advantage of NoSQL is the easily changeable data model.

If your DB is 3NF and you don’t do any joins
(you’re just selecting a bunch of tables and putting all the objects together,
AKA what most people do in a web app),
