possible, usually for technical reasons but sometimes for aesthetic ones.
The underlying Spring repository infrastructure will automatically detect these repositories, along with additional implementation classes, (thePresident:Movie {title: 'The American President'}),

This means we can persist all our changes in one go.

While you can use a narrower scope for this if you like, there is typically no advantage in doing so.For most request/response type applications SDN will take care of Session management for you (as defined in the Configuration section above).

(martin:Person {name: 'Martin Sheen'}), Without that important feedback we wouldn’t be where we are today.The Spring Data Neo4j (SDN for short) project, as part of the Spring Data initiative, aims to simplify development with the Neo4j graph This will be provided in a future release.Previous versions of SDN allowed you to use a DSL to generate Cypher queries. Cypher is declarative, and so usually the query itself does not specify the algorithm to use to perform the search. You can find graph databases used in areas as diverse as network management, fraud detection, cloud management, anything with social data, geo and location services, master data management, bioinformatics, configuration databases, and much more.Spring developers deserve access to the best tools available to solve their problem. Relationships can have an arbitrary number of properties.

Now, a year and half later, Spring Data Neo4j is available in its first stable release and I’m blown away by the result. Secondly, network requests containing redundant operations (such as updaing an object which hasn’t changed) are unnecessary, and have similar impacts. (martin)-[:ACTED_IN {role: 'A.J. (martin:Person {name: 'Martin Sheen'}),
CREATE (charlie:Person {name: 'Charlie Sheen'}), We can minimise the amount of data we send across the wire as a result, which leads to faster network interaction and fewer CPU cycles consumed on the server.A typical Neo4j HA cluster will consist of a master node and a couple of slave nodes for providing failover capability and optionally for handling reads.
Never before in any environment, in any programming framework, in any stack, has it been so easy and intuitive to tap into the power of a graph database like Neo4j.
