please, I need the clear code of this question because I have confusion about few steps

In this course, you will build a web application which is split into assignments 3,4 and 5. The description of the application is provided in part two. Part 1: How the application looks like? The index page shows-up with a log-in on the top corner of the web-page. In the index page, a random list of 10 most popular (most frequent purchased during the past 10 days) items is displayed. Once a user logs-in, he/she is able to: - Place an order - Cancel order If a user has not logged-in, he/she would not be able to place any order and should be redirected to the log-in page. Once logged in, the manager can view the list of all un-processed orders. A manager would be able to: - Manage stock: Add item to stock Remove item from stock Modify (price, name, quantity) a product The log-in id can be used to distinguish between a user and a manager. Part 2: Deliverables for Assignment 3: Write down the design for each of your model, view and controllers for the application specified in part one. - For each view, draw the components for that view. - List the models and for each model, specify the attributes for that model - Draw the UML diagram for each and every controller and the name of action methods used in that controller
