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

Chapter 5. Awesome Procedures on Cypher - APOC

Apoc was the technician and driver on board of the Nebuchadnezzar in the Matrix movie. He was killed by Cypher.

That was for those among you who know how Neo4j is tinted with Matrix love. However, that does not explain what APOC of in our context. APOC stands for both of the following:

  • A Package Of Components
  • Awesome Procedures On Cypher

Both are right.

Started in 2009, APOC is a collection of functions and procedures that are available for use in Cypher. They cover the following subjects:

  • Collection operations (sorting, min, max, and so on)
  • Graph operations (indexes and refactoring)
  • Text search
  • Conversions
  • Ranking
  • Geospatial operations
  • Data integration
  • Reporting
  • Getting a meta graph representing your graph

So, contrarily to the Matrix universe, Cypher does not kill APOC, not even the contrary.  APOC gives more procedures, more life to Cypher.
