We covered a lot in this chapter, and also saw the benefits of our earlier efforts. These benefits will become more and more apparent as we complete the solution. We placed the key business logic in classes, leveraged the number sequence framework, and touched on extending AX through event handling.

In the next chapter, we will get to use this information to add business intelligence and user interface helpers, showing how we can present key data to our users without them requiring to navigate away from where they are.
