What is it good for?

Social Graph

Recommendation

Available Software

• Ebay uses Neo4j - Java-based Graph Database-for delivery service routing

• Twitter uses FlockDB to store relationships among users

• RDF with SPARQL in research centers

Example

• Sara lives in Dammam, knows C# and knows MySQL. There is a job post that requires a candidate be in Dammam, know C# and know MySQL.

Graph Database Code

• We will be using a very simple language for representing the example as graph database. It is called N3.

• Both Jena or Euler engine can be used for inference (query).

• We need to represent data, then query it to get a matching result.
