Lets say in an application there are the following components
Database
|
|
V
DAOLayer
|
|
V
BO LAYER
|
|
V
Servlets
|
|
V
JSPs
What design patterns does the above incorporate?
My guess - DAO pattern.
Is this a good enough design for a SAAS(Software as a service) application?
What would be the drawbacks of this design?
How could this design be made better?
> my guess - DAO pattern.
Model 2, perhaps, among other patterns within the layers themselves (e.g., factory, builder, strategy, etc.).
