The Doctor has been captured in a graph.
See all the characters, actors, and even some of the props.
Try Neo4j right now on Heroku. It's easy:
Neo4j is a graph database. Records are called nodes and the connections between records are first-class citizens called relationships.
Neo4j refers to all of this as a Property Graph — nodes and relationships with key-value properties on both.
Querying is performed through a traversal, using the humane Cypher query language. It's like a friendly, pattern-matching version of SQL.
// Create the application
heroku apps:create {app name}
// Include the Neo4j Add-on
heroku addons:add neo4j --app {app name}
NEO4J_REST_URL environment variable to the driverThat the "relational" in RDBMS is simply a foreign key, a fairly humble reference to another record. Typically the column will be the same as the primary key in the other table, and the constraint will say something about the connection. To provide more information, use a...
Buried in the schema of every relational database on the planet, one or more join tables lurk. While the convention adds valuable information about how records relate, queries across multiple joins on large data sets can cause join pain.
In a graph database like Neo4j, relationships are essential data elements. Down to the bare metal, Neo4j is optimized for managing the relationships between records, resulting in queries that are 1000x faster.
In a graph traversal, only the local data affects the query speed, and because relationships are materialized as actual structures, finding local data is extremely fast. And, it isn't affected by the growth of the entire data set. What happens to your RDBMS join queries when the data set grows?
Gensen is a repository of Heroku project templates. These fully working example applications include just enough code to demonstrate how to use a particular combination of Language, Framework and Add-ons.
After signing in, you can easily browse the available templates, rate them, or elect to share one of your own projects. Many of the templates were contributed as part of the Neo4j Challenge on Heroku. You can read more about the challenge and the winners on the Neo4j Blog about it.
All you need to get started is an account on Heroku.
Congratulations! A fresh clone of the template project will be created for you, ready to use and easily customized for your own clever purposes.
Thanks! You will have very generously contributed to saving the planet by reducing the amount of energy wasted when starting a project from scratch.
The Wednesday track of NoSQL Now has been captured in a Neo4j Graph, deployed on Heroku. Neo4j's Webadmin is an easy way to get familiar with data and experiment with queries.
