Explanation / Answer

Deletion of the object from the list rundown is an extremely convoluted process, since all the subject records identified with the object must be altered. So keeping in mind the end goal to make the procedure less demanding, we can utilize place holders to erase the lists of various subject records. This technique is especially productive and savvy.

Thank you.
