Consider the process of ordering a book via Internet. Draw an activity diagram representing each step of the process, from the moment you open the shops web page to the point when you start reading the book, including login or registration. Include activities that others need to perform.

Add additional exception handling to the activity diagram you have developed. Model the following three exceptions:

1. The order got lost in the Internet 2. The wrong book is packaged 3. The ordered book is no longer available
