To answer that question, you need to see the post: Travel NoSQL Application – Polyglot NoSQL with SpringData on Neo4J and MongoDB.
Just a quick sample:
In this Fuse day, Tikal Java group decided to continue its previous Fuse research for NoSQL, but this time from a different point of view – SpringData and Polyglot persistence. We had two goals in this Fuse day: try working with more than one NoSQL in the same application, and also taking advantage of SpringData data access abstractions for NoSQL databases. We decided to take MongoDB and Neo4J as document DB, and Neo4J as graph database and put them behind an existing, classic and well known application – Spring Travel Sample application.
More than the usual “Hello World” example for languages and a bit more than for most applications.
It would be a nice trend to see more robust, perhaps “Hello World+” examples.
What is your enhanced “Hello World+” going to look like in 2013?
