In the tutorial we will work out the travel expenditure accounting system described in the chapter An Example. Actually we’re not going to implement a full blown application. But we will use classes from this problem domain to demonstrate the different capabilities of NDO which include

-     storing objects,

-     handling various types of relations,

-     working with polymorphic and non polymorphic inheritance,

-     implementing sophisticated queries with robust code.

We're currently working on a Github Repository to make the source code available.
