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
public class Person {
  //used by jo4neo
  transient Nodeid node;
  //simple property
String firstName;
  //helps you store a java.util.Date to neo4j
Date date;
  // jo4neo will index for you
String ;
  // many to many relation
Collection<role> roles;
  /* normal class oriented
  * programming stuff goes here
  */
}</role>
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
