In this chapter, we will be taking a much closer look at the real subject of this book,
that is, learning Neo4j—the world's leading graph database. In this chapter, we will
be going through and familiarizing ourselves with the database management system
so that we can start using it in the following chapters with real-world models and
use cases.
We will discuss the following topics in this chapter:
• Key concepts and characteristics of Neo4j
• Neo4j's sweet spot use cases
• Neo4j's licensing model
• Installing Neo4j
• Using Neo4j in the cloud
Let's start with the first topic straightaway.
