Case study

Book reading is an extremely healthy activity. It has many benefits and above all, it is exciting, entertaining and a great way to release stress, anxiety and depression. These are not the only benefits. Above everything; book reading helps in mental stimulation; improvement of memory and it also helps in improving language skills. It also certainly allows an individual to help concentrate better. In short, the benefits are enormous. 

In recent times we have been introduced to technologies such as laptops, cell phones, tablets and other technologies but to date, the conventional book reading is something that people cherish and enjoy in its own way. It is believed that a "book has no substitute" and book readers from all over the world firmly agree to this. 

Cynthia, a young technopreneur and a book lover; plans to open an online lifestyle substitute business named 'bookedbook.com'. This online business is Cynthia's dream. Cynthia has formally registered her new company, everything is in place from a legal perspective and the company now has ample funds to develop an online website that would support Cynthia's business idea. 

bookedbook.com would be an extremely interesting website. This website will require user registration. Children would also be able to register but their registration would be accompanied with some details of parents and their contacts. The website would only offer individual registrations and proof of ID would be a must when registering. bookedbook.com will offer quarterly, biannual and annual memberships. 

The whole idea is very simple. Registered book readers would be able to launch the books that they own and which they would want to give away to other registered members. A book launch would require complete details of the book. It would also require the user to provide the address where the book is available. Once the book details are provided by the subscriber (registered book reader) the company's content manager would approve the book launch request. Once approved, the book would be available for all users for them to review and/or acquire. The review process would allow all users to provide feedback and comments about the book and would also allow users to rate the book. The acquisition process would allow book readers to acquire the book from the book owner. The users planning on acquiring the book, would make a request for book acquisition. This request would help facilitate book reader meetup and exchange books. Once the book would be acquired the book owner would have the option of removing the book. 

bookedbook.com will also allow users to interact with one another via messaging and chat rooms. Users will be given an option to decide the mode of communication that they would prefer. Off course all chat request, messages and acquisition request and all other messages are also provided to the user via email that is provided at the time of subscription. 

The website would also provide a portal to the administrator for data analytics. Cynthia is keen to observe and analyse every type of data that is obtained at this website. For example, she wants to know which book is being exchanged mostly, she wants complete customer analytics, book exchange analytics, analysis of book reviews and rating and other similar portals for data analysis. 

As soon as the user registration would expire, all book launch requests would be halted by the system and the users interested in acquiring the book(s) placed by the user whose registration is about to expire would be sent an email that these book(s) are no longer available. Users would be asked to renew their subscription 15 days before the registration expiry date to ensure continuity of services. 

Cynthia does not want this website to be a book exchange platform only. She also wants the website to provide a platform for all the users to arrange for an online and face to face meetup. She wants to ensure that any book meetup events that bookedbook.com plans should be available to its users. Users should be able to register for these events which may be paid or unpaid. She feels that these meetups would be a great source of fun for book lovers and also a source of marketing for the company. 

In order to ensure this website stays profitable Cynthia also wants this website to allow book authors from all around the world to advertise their books on bookedbook.com. This functionality, however, would not require book authors to register with bookedbook.com formally. Book authors would be able to just fill in a 'book show request form', provide their details, provide the details of their book and a credit/debit card number. They would also provide information about the time period for which they want their book to be advertised on the website. Advertisement requests would also be approved by the content manager. Once approved, the book authors would be charged, and the advertisement would go live. The ad would be removed by the system automatically once it reaches the end date. bookedbook.com will only allow advertisement of up to 5 books at a time. All advertisement requests would be entertained by the system on a first come first serve basis. The advertisement functionality is also available for subscribers. In this case the fee for advertisement is very minimal. 

Cynthia wants this website to be upgradable and secure. She wants simple and modern interfaces and also wants a mobile application version of this website. 

Task 1. Create a Context Diagram for the given case study. 

Task 2. Create and document a Level 0 Data Flow Diagram (DFD). The Level 0 DFD should contain all the major high-level processes of the System and how these processes are interrelated. 

Task 3. Select three important processes from Level 0 DFD, decompose each of the processes into a more explicit Level 1 DFD.
