Shopping Cart Application

The Shopping Cart application enables an end user to search a

specific book in an online data base, place an order for it and

also purchase it online.

The application also enables you to manage a data stored in a

database for the online displayed books, such as:-

• adding a book,• adding a book category,

• modifying the book information.

To create the Shopping Cart application, we have used:-

• JSP as server side scripting language,

• JavaScript for client side data validations,

• HTML for data display,• Oracle as the database to store information.
