Exploring Neo4j, the NoSQL Graph Database

Rahul Sharma takes a look at Neo4j and some basic operations with graph databases:

Let us say we want to implement a use-case where there are persons and a person can be connected to other persons. In order to use Neo4J we must think about POJOs in terms of interfaces and corresponding implementions. This is so because the database is a key-value store at the back, so it asks us to store the properties of the POJO in terms of key-value pairs. Moreover there are no foreign keys in Neo4J, objects in the db are connected with other objects using Relationships.

Interestingly, he mentions getting some errors when trying to push 151K names. Sounds like he could use this Neo4j tip for handling long transactions.
