Thanks for working on this James! And indeed, contributions here are much
appreciated.

This is a concern part of the delivery mechanism or presentation layer.
Most of these exceptions are thrown from business objects in the domain
layer, which does not (or rather, should not) know about the delivery
mechanism. Excepts generally should not bubble up from the most specific
"lower layers" of a system all the way to the presentation layer. For
instance, one should never encounter a DBException outside of the storage
layer, as things outside of it should not know a database is used for
storage. DBException (or derivatives) might occur in your storage layer of
course, though these should be caught and dealt with appropriately (ie by
throwing a OrderUpdateFailedException). The same applies to most of the
newly added exceptions. The fault does not lie with the class throwing
them, but with something higher up in the call stack.
Unfortunately this is generally not done well within MediaWiki or SMW.
Perhaps this is not all that surprising if one considers that at many
places the separation of concerns is done at the character level :)
Cheers

Get your SQL database under version control now!
Version control is standard for application code, but databases havent
caught up. So what steps can you take to put your SQL databases under
version control? Why should you start doing it? Read more to find out.
