MVC (Model-View-Control) architecture is a widely used approach to decouple an applications logic into separate objects. For the online bookstore, there will be required a number of objects to complete the use cases. The MVC architecture of the book store is below:
Figure1.(msdn ,n.d.). MVC for Shoppingcart
Customers input search strings in the Book Search page. The Book Search Controller passes the searching criteria to Lookup Books for processing and redirects the display to Book Search Result page. While rendering of the view, Model will be requested to display the search result.
In the shopping cart, customers input books information in the Add to Shopping Cart page. The Add to Shopping Cart Controller passes the book information to Add to Shopping Cart for processing and redirects the display to Shopping Cart Result page. While rendering of the view, Model will be requested to display the result.
