It is billed as the ‘World’s Leading Graph Database’.
It is a different kind of database if you are thinking about relational databases like SQL Server, Oracle etc. Graph database is all about nodes(vertex) and relationships(edges)between nodes. Both nodes and relationships have properties. On the surface it does not seem to have the rigidity of relational databases in terms of integrity relationships, but I have only skimmed the surface. If relational databases are synonymous with set theory, the Graph databases seems to lean on graph theory. These considerations apart it appears to be well suited for social networking and non-structured data. Well it may not be a good fit for relational data. Who knows the ‘relational people’ may add other hooks to do the same.

This one on Mozilla.
