Class Model

java.lang.Object
  ch.claudio.contactdb.Model

public class Model
extends java.lang.Object

The model will contain all procedures to be called from the different views.

I switched in the early phase from using a traditional SQL database to db4o. Beeing this the first project where I use an object database, and as with an object database you just store your instances instead of having to create SQL statements, I refreined of having a special class for handling the databse. This, because in my first attempt at an object db design I would not know yet, where the separation line between this and the DBInterface module would be.

The structure of the database is defined through the classes in the ch.claudio.contactdb.data package.
