I'm hearing a lot recently about NoSQL databases, particularly MongoDB. I'm interested to know what the implications of changing to a MongoDB database is within the context of a Ruby on Rails appplication.
I haven't been able to find an article that gives a good description of how things vary from using an SQL database when using MongoDB.

Thanks.
