This article is the second in the NoSQL databases series, where we will explain different NoSQL database technologies, and how to integrate them with SQL Server databases.
Then we will give a step-by-step guide on how to install and get started with Neo4j on Windows operating system. In this article, we will talk briefly about graph databases and what Neo4j is.
