11 Introduction to Neo4j

We all have our own graphs...

Knowledge graph: beyond links, search is smarter when considering how things are related Facebook graph search: people are most interested in finding things in their part of the world You: have relationships to people, to organizations, to places, to things -- your personal graph

55 And why now?

A graph... ๏ you know the common data structures linked lists, trees, object "graphs" ๏ a graph is the general purpose data structure suitable for any data that is related ๏ well-understood patterns and algorithms studied since Leonard Euler's 7 Bridges (1736) Codd's Relational Model (1970) not a new idea, just an idea who's time is now

A graph database... ๏ optimized for the connections between records ๏ really, really fast at querying across records ๏ a database: transactional with the usual operations ๏ “A relational database may tell you how many books you sold last quarter, ๏ but a graph database will tell your customer which book they should buy next.”

We're talking about a Property Graph

Neo4j is a Graph Database ๏ A Graph Database: a Property Graph containing Nodes, Relationships with Properties on both perfect for complex, highly connected data ๏ A Graph Database: Embeddable on the JVM high-performance with High-Availability

10 Questions 1. Why graphs? Why now? ★ a new perspective on the same data 2. What's a graph database? ★ a database for connected data 3. How do people use Neo4j? 10

[A] Mmm Pancakes[B] ACL from Hell[C] Master of your Domain Real World Use Cases:

Why Neo4J? ๏ The internet is a network of pages connected to each other. What better way to model that than in graphs? ๏ No time lost fighting with less expressive datastores ๏ Easy to implement experimental features This Material is subject to the terms of the Mozilla Public # License, v If a copy of the MPL was not distributed with this # file, You can obtain one at
