Reattaching Databases - Some Code AND a Contest!

Data Warehouse Version Management
In most tables it is enough to have a stored procedure that performs Update Else Insert logic for data managment. However, in some cases we do not want to destroy the old data with an update statement. Instead we want to maintain history up to a certain number of versions.
