MongoDB isn't really an OODB - it makes no attempt to store actual class instances w/ methods, etc, but stores "documents", which are JSON like structures. What's really nice about this is that it is a very natural mapping to datatypes that are already present in most languages, like Python dictionaries and Ruby hashes (and JS objects).
We use the word "document" to refer to the structures stored in the database, but it isn't really meant to mean a document like a file on the filesystem (although MongoDB can handle storing large files - check out GridFS). When we say "document" we just mean this JSON-like structure, which can be more complex than a key, value pair or even a row in a traditional RDBMS (i.e. documents can embed other documents, etc.)

Internally, MongoDB uses memory mapped files to store data on disk. This keeps the main database code clean and simple, but causes some problems on 32-bit platforms. If you run MongoDB on a 32-bit system, you can only store about 2 GB of data. 64-bit systems are effectively unbounded.
