Electronic commerce, also known as ecommerce is a type of industry where buying and selling of a product is conducted over electronic systems such as the internet. The purpose of this application is to bring knowledge to students about ecommerce and how an interactive ecommerce application can be designed from scratch using client-side languages, such as JavaScript and HTML, combined with the server-side Java language through Java Server Faces. The server side, mostly Java, contains all the implementation related to setting up the database, creating session models for joining different user-interface (UI) pages, calculating the shipping costs and sales tax, etc. It is responsible for taking information from the database and making it available to the UI by mapping the category or item ID to the respective IDs stored in the database. The client side is responsible for showing the entire user interface, containing the CSS, HTML, and JavaScript.
