Graph-based nosql Database: neo4j

What is neo4j?

1. A high-performance graph relational model database 2. A nosql database 3. multiple types of support Programming Language 4. How can I delete nodes related to a node in neo4j, which is good at processing model data with multiple relationships? 1. Find all links of the target node 2. Start a transaction, delete the Start Node or end node3. traverse all the nodes found and delete the relevant relationship4. then delete the node itself and submit a transaction.

 1   Public   Static   Void Deleterelativenode (node N ){
 2 Traversaldescription TD = traversal. Description (). Relationships (types. Relative, direction. Both)
 3 . Evaluator (evaluators. excludestartposition ());
 4 Traverser T = TD. Traverse (N );
 5           For (Node TN: T. nodes ()){
 6 Iterable <relationship> relationships = tn. getrelationships ();
 7               For (Relationship R: Relationships ){
 8                   If (R. getstartnode (). Equals (n) | r. getendnode (). Equals (N )){
 9 R. Delete ();
 10 }
11 }
 12               If (! Tn. hasrelationship ()){
 13 Tn. Delete ();
 14 }
 15 }
 16 }

A condition for deleting a node in neo4j is that the node does not have any relationship.
