IT Computers Sequence

This is a sequence diagram based on the IT Computers case study. In it the customer is visiting the company website and compiling an order.

I think we looked at this process in class. It was very helpful to learn about the concept of an Order Line from Helene, I has previously only thought of having "order" as one item but a system that works this way is clearly not going to be very dynamic as if there was a problem with one item of the order the whole order would have to be scrapped. With an order line each part of th order can be considered individually to make compiling an order a better process.
