@fedeisas - Don't get carried away by the speed. Thats not really the point about NoSQL. If your application deals with only a million records or so you aint gonna see any increase in speed. As Bretticus has pointed out the thing about Document oriented DB's is that they are not like table oriented "classical" Databases. The SQL DB's that we have been using for the past 30 yrs or so are two-dimensional (row x column). Many NoSQL DB's are multidimensional. Just think of a record as a multidimensional array.

@Stilly: Thanks for your answer. I've heard before that sites like Facebook uses MySQL for some things (let's say the user table) and Casandra (NOSQL) for things as friends sugestions. I mean, I believed that complex things to calculate, that would require MEGA complex queries, Facebook precalculate them and store them as key/value on some NOSQL systems, so they could get the data as fast as possible. But, I repeat, that's what I used to think. In my web developing experience, I have never faced that level of speed requirements (unhappily!), but I'm interested in learning new stuff
You think I can run MongoDB on a hosted server?

Thanks for sharing
