Summary

This chapter covered basic error handling structures and briefly examined the base Exception class. It also reviewed strategies and reasons for enterprise error handling structures and why they are different. You created a flexible, robust, and extensible set of classes for handling and storing almost every conceivable error. In addition, the application can report those errors to technical support regardless of the status of the database.

Using the strategies for error handling in this chapter, the technical support response time of any organization has the potential to become much faster and more efficient.

In the next chapter, you will start looking at the important part of any application—business rules. You will examine what they are, how to handle them, and how to report violations to the user. You will examine object state, make your objects more aware of their own state, and give them the ability to communicate that state to the user interface.
