Hmmm, are user errors so frequent that you need a mechanism for this? It seems, you might either need to better educate your users or control access in a way that no damage can be done. Depending on the application at hand and the nature of errors I can think of a number of ways to do this, e.g. constraints, staging area where changes are entered and are only propagated to the main data if a second user confirms them.
Just a few thoughts.
