Learning Neo4j 3.x - Second Edition

By: Jerome Baton

Overview of this book

Neo4j is a graph database that allows traversing huge amounts of data with ease. This book aims at quickly getting you started with the popular graph database Neo4j. Starting with a brief introduction to graph theory, this book will show you the advantages of using graph databases along with data modeling techniques for graph databases. You'll gain practical hands-on experience with commonly used and lesser known features for updating graph store with Neo4j's Cypher query language. Furthermore, you'll also learn to create awesome procedures using APOC and extend Neo4j's functionality, enabling integration, algorithmic analysis, and other advanced spatial operation capabilities on data. Through the course of the book you will come across implementation examples on the latest updates in Neo4j, such as in-graph indexes, scaling, performance improvements, visualization, data refactoring techniques, security enhancements, and much more. By the end of the book, you'll have gained the skills to design and implement modern spatial applications, from graphing data to unraveling business capabilities with the help of real-world use cases.

Preface

The license conditions


For the slightly more complicated bit, Neo Technology has chosen very specific licensing terms for Neo4j, which may seem a tad complicated but which actually really support the following goals:

  • Promoting open source software
  • Promoting community development of Neo4j
  • Assuring long-term viability of the Neo4j project by providing for a revenue stream

This is achieved in the following ways:

  • The Community Edition uses the GNU Public License Version 3 (GPLv3) as its licensing terms. This means that you may copy, distribute, and modify the software as long as you track changes/dates of in-source files and keep modifications under GPL. You can distribute your application using a GPL library commercially, but you must also provide the source code. It is therefore a very viral license and requires you to open source your code--but only if your code directly interfaces with the Neo4j code through the Java API. If you are using the REST API, then there are little or no contamination...
