I\'ve got a rather large SQL Server 2005 database that is under constant development. Every so often, I either get a new developer or need to deploy wide-scale schema change
I suggest using RedGate's tools (this is not advertisment, but real life experience with them) that can deploy schema changes and/or data:
I used these tools in the past (others as well) and they really helped with development staging process. These tools aren't free but their price is more than acceptable for any development team.
