Summary
In this chapter, we have introduced how to handle business logic. We first taught you how to use fallbacks to handle situations where the system cannot process a user's needs. Then we introduced the rule policy that can use predefined logic to execute a fixed action. Finally, we introduced forms that can automatically interact with users to gather the information that is needed by the task. We also built a weather forecast chatbot to help you understand those concepts better.
In the next chapter, we will discuss how to handle chitchat and FAQs.
