when about differences between MongoDB and a graph db such as Neo4j?

Document Databases (such as MongoDb) are very similar to GraphDBs (such as neo4j). The big difference is the ability of a graph database to create relationships between the nodes. A small note on terminology: what a GraphDB calls a node is very similar to a document in a document database. The relationship component of the GraphDB allows for very quick querying of data.

Hi Alessandro,
There are quite a few differences. The primary purpose of a graph database is to represent graphs and provide easy traversal of them. MongoDB, on the other hand, has been build as a generic data store with a rich query language that can replace a relational database or a key-value store for a number of use cases (web applications, e-commerce, caching, sessions storage, analytics, etc.).
