Summary

In this chapter, you learned about what NoSQL databases are and how important a role graph databases play when datasets are large, complex, and inter-related. You also learned about the different modes of operation of Neo4j, namely, embedded, server, and high availability, and how to configure each of them. Also, Neo4j is easy to set up in cloud deployment environments such as Amazon Clusters and Windows Azure, which offer native built-in support for Neo4j as a scalable database management system.

In the next chapter, we will be dealing with how to efficiently query Neo4j and also study the indexing support that can be used to optimize traversals.
