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.

Do we still have database migrations? Relationships? Will has_one still work? What are the current adapters like?

Thanks.
