DESCRIPTION
Join us as we enhance the Chatter experience by building Social Graph utilities on Heroku. Using the power of the neo4j graph database to generate a representation of the relationships between people in a large Chatter community, we can provide some cool features, such as a visualization of the graph, and a degrees of separation tool. Exposing this via Canvas will give the user a rich, enhanced, native Chatter experience. This is a good example of handling complex tasks on Heroku that cannot be easily handled on the salesforce.com platform.

AgendaThree things I want you to leave with

Why social graph utilities for chatter• Understanding how people are related (in large communities)
• Shortest path between two people (like Linked-in)• Visualizing a graph to spot “silos”
Genesis/AcknowledgmentsHow this got started
▪ ACT, large social network application▪ DifferentSpokes (Michael Hunger)▪ William’s “Chatter Liasons” (groovy)
A sample chatter graph
Why Heroku/Canvas• Imagine the “shortest path” problem using SOQL…• Trivial with graph databases like neo4j
• Demo
• But we still want to see it “natively” in Salesforce.com
Graph databases, a primer
A graph database stores data in a graph, the most generic of data structures, capable of elegantly representing any kind of data in a highly accessible way
