Book description

Design, build, and administer scalable graph database systems for your applications using Neo4j

  • Explore the numerous components that provide abstractions for pretty much any functionality you need from your persistent graphs

  • Familiarize yourself with how to test the GraphAware framework, along with working in High Availability mode

  • Get an insight into the internal working of Neo4j and learn about some useful tools, administrative configurations, and security tweaks built for it

    • In Detail

    This book provides an insight into working with Neo4j; deployment, configuration, and optimization of the data models; and utilizing storage for better performance.

    This book covers all aspects related to working with Neo4j, including querying, indexing, modeling of graph data, testing, and deployment of your Neo4j applications, and also shows you the internal features of the Neo4j graph database. With a sample demonstration and outline of community developed tools, this book will help you develop cutting-edge, high performance, and secure applications for complex data using the Neo4j graph database.
