Presentation Transcript

  1. Neo4j Adam Foust

  2. Road Map • Introduction to Neo4j • NoSQL databases • Graph databases • How Neo4j works • Comparison

  3. Introducing Neo4j • Introduced in 2010 • Open source • Java-based • NoSQL Graph Database

  4. NoSQL databases • Four classes of NoSQL databases • Key-value store • Amazon’s Simple DB • Column-family or big table databases • Google’s Big Table • Apache Cassandra database • Document-oriented • MongoDB • Graph Databases • Neo4j

  5. Graph Database • Neo4j is a graph database • Database full of linked nodes • Stores data as nodes and relationships

  6. Graph Database (cont.) • Nodes represent entities • Edges represent relationships • Connections between data are explored • Faster for associative data sets • Intuitive • Optimal for searching social network data

  7. How Neo4j Works Storing Objects • Domain objects take a node • Jo4neo framework 

  8. How Neo4j Works (cont.) Dealing with complexity • Simple domains can be complex • Mutual Friend example

  9. Case Study • A side by side comparison of a relational database and Neo4j • Artificially generated graph dataset with natural statistics • 1 million vertices and 4 million edges

  10. Case Study Results • First 250 vertices used as roots

  11. Result Conclusion • Neo4j proved to take less than half the time of the SQL database. • Neo4j is optimal

  12. Conclusion • Introduced Neo4j • Discussed NoSQL databases • Went over graph databases • How Neo4j works • Case study
