Question

Answer 1

The user doesn't need to know there was a database exception, the developer does.

The specific exception should be logged. The user should see that an operation failed. Generally you'd either simply report this through normal S2 means, e.g., an error message.

You may also throw an application-specific exception and use S2's declarative exception handling.

You may use declarative exception handling to handle any or all low-level exceptions, but IMO that's either too general, or too tedious.
