This is quite similar to a training course I recently put together for a
London start-up. The first day covered graph theory, the Neo4j product
itself and then delved deeply into Cypher. There were then a number of
Cypher exercises which could all be carried out through the neo4j-shell.

The second day talked about the server API and py2neo plus some best
practice material and some more (domain-specific) exercises. There was
nothing included on Java embedded usage as it wasn't required in this case.

The Cypher workbook is generic though so if you're interested in using it,
let me know and I'll send it over.

Cheers
Nigel
