Can someone please explain me what an unplanned DML request is? According to the book I read, an unplanned request is an ad hoc query, a request for which the need was not seen in advance. Can you please give me an example?
For example, when you have a bug in Component and it makes some corruption in Database. (it could be wrong version of procedure which count Taxes)
In this case, you could need to use ad-hoc query to bring back consistency of data.
