Relationships are not really given any consideration here. The idea here is not to emulate the relational databases. So in a relational sense the join relationships are not supported.
Nevertheless there is an inherent relationship between nodes. For example each node has a set of key/value pairs. This set will yield 'n' number of independent orthogonal loops (or tables).
