Comprehensive Example

I would like to see an example project that demonstrates a complex design from the high level concept down to actual code. Most helpful, for a newbie like me, is to see how common programming scenarios are demonstrated and any best practices. Since this product is none linear in nature this would help in learning how ot break problems down so that they can be mapped out using this tool. I purchased the book “Object Oriented Technology from Diagram to Code using Visual Paradigm for UML” which I have found to be extremely helpful but I still would like to see a complete complex example.
