The problem domain is the same as that you came across earlier in Assignment 1. For convenience its description is reproduced below. Also, following the domain description, is provided a simplified relational data model for the problem domain. Domain Description This case study deals with a system used by a Book Shop Chain, known as Sydney Book House (SBH). The information to be stored in the system includes four major categories of data: branch information about SBH, author information, book information, and publisher records. Information about employees of SBH and other relevant data are also stored in the system. A. Branch Information: SBH has several branches all over Sydney. The system shall contain a branch name, an ID number, address and number of employees working at that branch. B. Author Information: The system shall contain a list of author identifiers along with author name and author email address. C. Book Information: The system shall contain a list of unique book identifiers including book title, book type (e.g. fiction, history, educational), price of that book and whether it is paperback or not (yes/no). The following business rules are operative: 1. Each book is published by a publisher who is listed in the system. A publisher may or may not publish any books. 2. Each book must be written by at least one author. There may exist multiple authors for a book. In this case, the author sequence must be maintained as in the cover page of the book. Of course, an author can write many books or she might be waiting to publish her first book
