Designing for Scalability with Microsoft Windows DNA (DV-MPS Designing)

Figure 8-1 highlights the differences between the facade class before reengineering and the facade class after reengineering.

Figure 8-1. The fcdHorseMaint facade class before and after reengineering.

To the left, you can see the method set of the facade class before reengineering, and to the right, the one after reengineering. Notice the following two new methods, both of which were in fact added in Microsoft Visual Basic and then reengineered into the model:

• GetCountryList delivers a recordset containing all the countries in which horses might be bred.
• GetTrainerList delivers a recordset containing the names of all the trainers. It can also return a subset of all those trainers whose names fit the name pattern given to the method in the strLastNamePattern argument.
