For first-time users, if you don't know much about the tool, I think you should go with a document-based DBMS tool. I had to use the tool because I learned about it in college. My advice to others is that they need to learn about the tool, nodes, and vertices and then purchase Neo4j Graph Database. It will be a little bit difficult for new users to know what is the meaning of a node, what vertices are, how to use it, or how an application can use it. The tool is easy for new users as it is an intuitive tool. I rate the tool a nine out of ten.
