For changes, you can add a datetime column to the table called ‘LastModified’ or something like that, and write the current date/time to it every time you write a record.

Alternatively, if you need to know when a record was deleted you can write a trigger that intercepts inserts/updates/deletes to the table in question, and write the timestamp value to another table, along with identifying information about the affected record.

The best way is to implement ‘soft deletes’ where a record is marked with some kind of status value (e.g. a ‘IsDeleted’ column) that can be flipped and subsequently ignored by other code in the application when reading from the table.
