Can I configure an SQL Server 2008 DB so that it will save all empty strings as NULLs?

null

In my current project it would be convenient to exclude empty strings from the domain, so that is an empty string is met wherever, it is treated as NULL, for example if I UPDATE [table] SET [Something]='', SQL Server should treat it as SET [Something]=NULL, so that in next SELECT a NULL is returned as [Something] value.

Should I use triggers or there is a better way?
