Design Patterns Explained (1) – Tranditional Design

Part II? Limitations of Traditional Object-Oriented Designed

作者舉了一個需求的執行個體, 並在此需求上用OO方法給出一個設計方案.
這個方案雖然使用OO方法設計的, 但還是作為反面教材給出的.
在下面的章節裡作者應該會給出符合Design Patterns的設計方案.

這個設計方案不好的原因在於:
?????? ?too much attention to details too early.

下面是作者的總結
??????? One common?problem that we analysts can have is that we dive into the details too early
in the development process. It is natural because it is easy to work with these details.Solutions
for the details are usually apparent, but are not necessarily the best thing to start with. Delay as
long as you can before you commit to the detail. ...

作者還提到他感覺這個設計不好大部分是因為直覺(本能)
?Pay attention to your instincts
Gut?instinct is a surprisingly powerful indicator of the quality fo a design.
I suggest that developer learn to listen to their instinct.
