depending on your requirements and implementation of these, you might want to
have a look at "Developing Time-Oriented Database Applications in
SQL" (https://www2.cs.arizona.edu/people/rts/tdbbook.pdf). It is quite thick
with 530 pages, but it helped me wrap around my head on a similar
requirement. It describes the challenges with tracking and managing these
kinds of changes as well as solutions together with SQL examples.
Cheers,
Christian
