10. Putting It All Together

We’ve created all the parts of the app now—a data model along with the behavior needed to update the model from the Internet; classes to present the data in views; and controllers to take care of the application’s workflow. What we haven’t done yet is put these classes together to make a complete, functioning application. Hopefully, the work we’ve put into designing these classes to be used and to work in isolation means it won’t be too hard to construct the app.
