As part of the work in this chapter, I also completed the refactor for the sales order processing module. In doing so, I built out a new read model with a ViewBuilder class and View to support the SalesOrder entity. I will not go over all of that code here, because, for the most part, it's on par with what we just covered for book. I will highlight some of the differences here though.
