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

Neo4j spatial


Neo4j Spatial (later NS) is a plugin, like APOC, discussed in Chapter 5, Awesome Procedures on Cypher - APOC. The homepage of this plugin is https://github.com/neo4j-contrib/spatial.

Just like APOC, you should take care to install a version compatible with the version of your Neo4j server. See the releases tab on their GitHub landing page. The release notes and the release filenames are self-explanatory. (Thank the project leader, Craig Taverner.)

Online demo
