A gist to demonstrate the power of Neo4j for dealing with hierarchical data.
//Let's create the top of the tree, the PRODUCT
create (n1:PRODUCT {id:1});
//Let's create 100 children of the PRODUCT, COST_GROUPS connected to the top of the tree
match (n1:PRODUCT {id:1})
with range(1,100) as RANGE, n1
foreach (r in RANGE | create (n2:COST_GROUP {id:r})-[:PART_OF {quantity:round(rand()*100)}]->(n1) );
//for every COST_GROUP, let's connect 100 children at a 3rd level, the COST_TYPEs
match (n2:COST_GROUP)
