Deletes on enterprise SQL systems are usually prevented (the preferred pattern is "mark for delete + purge" similar to a VM's garbage collection). The Application ignores "marked" data as deleted.

That leaves tracking the remaining inserts and updates, which is a well understood problem. It's called Auditing. Here is a simple script that will auto-audit a SQL Server database... variations in other SQL dialects are likely just as straighforward.
