The IMDB example 1.0, a Neo4j-based web application using part of the IMDB actors/movies dataset, has been released. The application lets the user search for or browse through actors and movies. For actors, it also shows their Bacon path as well. Here's how it can look:
The application itself is accompanied by thorough instructions and explanations. This way you can learn how to model a domain using the graph database paradigm inherent to Neo4j. Other important points is organizing data for searches, finding paths and handling transactions.
One nice thing about Neo4j is its whiteboard friendliness. This is a sketch of the IMDB domain model ... no, wait, it's the implementation:
For those who want to get started right away, here's a quick how-to (requiring mvn and svn to be already installed). Enter the following at the command line (all at once):
mkdir imdb &&
cd imdb &&
mvn scm:checkout -DconnectionUrl=scm:svn:https://svn.neo4j.org/examples/imdb/tags/1.0/ &&
cd target/checkout &&
Then browse to http://localhost:8080/imdb/setup.html to load the data and use the application. Use ctrl-c in the same console to stop the application.
From the main page of the Neo4j IMDB example you will find your way to the location of downloadable zip files as well if that's what you prefer.
