Overview of this book

Neo4j is a graph database that includes plugins to run complex graph algorithms. The book starts with an introduction to the basics of graph analytics, the Cypher query language, and graph architecture components, and helps you to understand why enterprises have started to adopt graph analytics within their organizations. You’ll find out how to implement Neo4j algorithms and techniques and explore various graph analytics methods to reveal complex relationships in your data. You’ll be able to implement graph analytics catering to different domains such as fraud detection, graph-based search, recommendation systems, social networking, and data management. You’ll also learn how to store data in graph databases and extract valuable insights from it. As you become well-versed with the techniques, you’ll discover graph machine learning in order to address simple to complex challenges using Neo4j. You will also understand how to use graph data in a machine learning model in order to make predictions based on your data. Finally, you’ll get to grips with structuring a web application for production using Neo4j. By the end of this book, you’ll not only be able to harness the power of graphs to handle a broad range of problem areas, but you’ll also have learned how to use Neo4j efficiently to identify complex relationships in your data.

Questions

  1. US states:
    • Find the first-degree neighbors of Colorado (code CO):
      • What are the codes of these neighbors?
      • Can you count how many there are using an aggregate function?
    • Which states have the highest number of neighbors? The lowest? Think about the ORDER BY clause.
  2. GitHub graph enhancement:
    • From neo4j_repos_github.json, can you save the project language when provided, as a new node? You can use the new Language node label.
    • Can you also save the license, when provided, using a new node? Use a Licence node label and save all of the provided information from GitHub as properties.
      (Hint: the license is provided with the following format):
   "license": {
"key": "other",
"name": "Other",
"spdx_id": "NOASSERTION",
"url": null,
"node_id": "MDc6TGljZW5zZTA="
},
    • Using the GitHub API, can you save the user locations?
      Hint: the URL to get user information...
