In many architectures, such as the three- and four-tier architectures (Figures 6-21 and 6-22), the storage of persistent objects is handled by a dedicated layer. In your opinion, which design goals have lead to this decision?
What will be an ideal response?
Portability: Separating the application from the details of storage allows the storage layer to be replaced by a different
one (e.g., switching database management systems).
Robustness: It is easier to guarantee the integrity of the stored data if it is handled by a single layer.
