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

Unmanaged extensions


Unmanaged extensions (UE) are a way to serve content from the Neo4j server but outside of its usual API endpoints. Strictly put, this is YOUR code, running on the server, in order to serve your data. More precisely, this is JAX-RS 2.0 code.

Note

JAX-RS is a Java API originating in Java EE 6, whose goal is to help develop web services according to the Representational State Transfer (REST) paradigm. The corresponding JSR is #339, and its expert group is constituted of Java gurus such as Adam Bien or Bill Burke.

In order to create a Maven-based project, after the initial creation with your favorite IDE, add those two dependencies to the pom.xml file:

<dependency>
  <groupId>org.neo4j</groupId>
  <artifactId>neo4j</artifactId>
  <version>${neo4j.version}</version><!-- This is a Maven property  -->
  <scope>provided</scope>
</dependency>
