What is Neo4J graph database?
This article is about Neo4j – one of the most mature and full-featured graph databases on the market today. Graph databases approach the task of data modeling with the view that many things in life lend themselves to being represented as a collection of nodes (V) and connections between them called edges (E).

DELETE keyword can be used for permanent removal of nodes or relationships from the graph:
What is OGM in Neo4J?

Java Driver
- So far we've been looking at interacting with an embedded Neo4j instance, however, in all probability for production, we'd want to run a stand-alone server and connect to it via a provided driver. First, we need to add another dependency in our maven pom.xml: You can follow this linkto check for the latest version of this driver. Now we can establi...
JDBC Driver
- It is also possible to interact with Neo4j via a JDBC driver. Yet another dependency for our pom.xml: You can follow this linkto download the latest version of this driver. Next, let's establish a JDBC connection: Here conis a regular JDBC connection which can be used for creating and executing statements or prepared statements:
Object-Graph-Mapping
