You are developing a system that stores its data on a Unix file system. You anticipate that you will port future versions of the system to other operating systems that provide different file systems. Propose a subsystem decomposition that anticipates this change.
What will be an ideal response?
A Bridge pattern should be used to define a generic interface to the storage subsystem. Consequently, different
implementations of the storage subsystem can be provided to dealing with specific file systems. Note that the Bridge
pattern does not address the problem of moving files from one file system to another. To address this problem, a
separate conversion utility needs to be developed.
