Time and Time Again: Retroactive Updates

The past six columns illustrated an asserted versioning original insert, update and delete and, in the last column, introduced a taxonomy to guide the remainder of our work.

These three transformations are the most basic ones in the sense that they correspond to inserting, updating and deleting in non-temporal tables.
