Here we are going to understand the functional overview of the FlixOne bookstore application. This is only for the purpose of visualizing our application. The following is the simplified functional overview of the application until Shopping cart:
In the current application, the customer lands on the home page, where they see featured/highlighted books. They have the option to search for a book item if they do not get their favorite one. After getting the desired result, the customer can choose book items and add them to their shopping cart. Customers can verify the book items before the final checkout. As soon as the customer decides to check out, the existing cart system redirects them to an external payment gateway for the specified amount you need to pay for the book items in the shopping cart.
As discussed previously, our application is a monolithic application; it is structured to be developed and deployed as a single unit. This application has a large code base that is still growing. Small updates need to deploy the whole application at once.
