Also, new Transaction support in the shell let's you call for a do-over in case you misstep. RELATE, a Subgraph Match-Maker A RELATE clause looks a lot like a MATCH clause — the ASCII-art of graph traversals — but behaves differently when there isn't a satisfying subgraph.

Uniquely, at this 1.8.M02 merge point, the changes are all of the strong, silent type: under-the-hood improvements, stage-setting additions, or simple issue-correcting.

Sometimes, you just want to fast see what you are putting in your little example graph. In Neo4j, there is a well hidden gem-the Graphviz Component.

Here is the short version: First, choose to create a new maven project: Second, choose the default maven quickstart archetype for it: Now, after choosing a package namespace and project artifact id, wait for the project to created and go to the dependency tab of the pom.xml.
