The Book-O-Rama Shopping Car Problem

• Need to connect database to user’s browsers, so they are able to browse items by category

• Users should be able to select items for later purchase

• When they’re done, you need to total their order, take delivery details, and process payments

• You will need an administration interface so that administrators can add and edit books and categories
