This would be a feature of the relatational database engine (when designed specifically for that ). In a non-relational database the programmer would have to write code to be able to do that. Of course this feature may not be utilised in a RDBMS and you may write code to control your deletes and updates. I have done both and much prefer the database engine to do what it is designed to do !
