Chapter 9. Data Safety
A database application that does not ensure its data is safe is not very useful. An application that allows a user to work for hours processing customer data and then lets the user accidentally exit without saving the changes will cause more frustration than it is worth.
This chapter explains how an application can ensure that its data is safe before the user exits. It shows how to implement the standard File menu commands New, Open, Save, and Save As. It also shows how to build a most recently used (MRU) file list. Some of these techniques were used in previous chapters. This chapter explains them in more detail.
