Review the original system description in Chapter 2, additional project information in Chapters 3, 4, 6, 8, and 9, and the use case diagram shown in Figure 12-25 to refamiliarize yourself with the proposed system. Complete these tasks:

1. For the moment, assume that the database will store two glucose levels for each patient—normal minimum and normal maximum—and that an alert will be generated if three or more consecutive glucose readings are above or below those levels. Expand the domain class diagram in Chapter 4 to include this information and then develop a first-cut design class diagram to support the patient use case View/respond to alert.

2. Develop a design solution using CRC cards for the View/respond to alert use case.
