I'm a single developer/DBA/chief cook & Bottle washer at my company. I use Subversion tied into Visual Studio and SSMS/Windows Explorer.

I actually like using Explorer as my navigation shell, Win 7 makes grouping and searching different types of stored procedures quite simple, with editing etc. in SSMS.

There's nothing quite like knowing I can roll back a change or get back an accidentally deleted SP or VS file. 😎 I would recommend version control for any project that changes frequently. The only things I don't put in version control are the ERD and a few Access tools that do the grunt work of creating CRUD SPs.

Plus it gives an additional layer of backup, another copy is never amiss when something goes south!
