ABSTRACT 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.

ACKNOWLEDGMENTS I would like to express my deep sense of gratitude and convey thanks to everyone who helped me and supported during the completion of this project and my research paper. First, I would like to express a deep sense of gratitude to Dr. Kendall Nygard for helping, guiding, and supporting me throughout my master's degree and research completion. I also convey thanks to my all committee members for helping me from time to time and for being on my committee. I acknowledge my department for providing the courses and a great atmosphere that helped complete different chapters of this paper. I especially thank my supervisor, Mickey Arora, for supporting me and my concepts and for allowing me to do something the way I liked, as well as my company, Thomson Reuters, for helping me develop the skills necessary to design this application as part of my master's research. Last but not least, I would like to thank my family members for their constant and unrelenting support towards my education and for their impartial love for me. I would also like to thank my friends, without whom this project would have been impossible.
