Introduction toNeo4j

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

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 customerwhich book they should buy next.”

We're talking about aProperty 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

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
