Building An Application

1. Incremental development
   • Don’t specify everything before starting
   • Requires close cooperation with users
   • Discovering mistakes early makes changes cheaper
2. What your application does (Depot, a shopping cart)
   • Depot’s use case:
     • Two roles: buyer and seller
       • Buyer browses, selects, and purchases products
       • Seller maintains product lists, checks orders awaiting shipment, and marks orders as shipped
     • Page flow for buyers
       • Catalog page
       • Cart page
       • Checkout page
       • Receipt
   • Page flow for sellers
     • Login
   • Menu
     • Product maintenance
       • Create
       • Show
     • Show pending orders
   • Data
     • Product
     • Seller details
     • Line items
     • Orders
