1)Draw a class diagram representing a book defined by the following statement: “A book is composed of a number of parts, which in turn are composed of a number of chapters.

Chapters are composed of sections.” First, focus only on classes and associations.
Add multiplicity to the class diagram you produced.
Refine the class diagram to include the following attributes:
• Book includes a publisher, publication date, and an ISBN
• Part includes a title and a number
• Chapter includes a title, a number, and an abstract
• Section includes a title and a number
Consider the refined class diagram. Note that the Part, Chapter, and Section classes all
include a title and a number attribute. Use inheritance to factor out these two attributes . Also, separately draw the model an online bookstore considering the process of ordering a book via Internet. Draw an activity diagram
representing each step of the process, from the moment you open the shop’s 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
