I stumbled over two articles from ”ChiMu Publications”, namely Tuple-Marks: NULLs everyone can live with  and Foundations of Object-Relational Mapping.  They are both quite old (1997), and I would assume that you have seen/read them, and possibly debunked them.

 

After a first reading, it seems to me that the author(s) are not completely ignorant. Do you have an opinion on the articles you would share to make a critical reading, well, more critical?

We have come to the conclusion that many-valued logics and NULLs are not the correct solution for relational databases, regardless of any details. We do not consider sources on that topic a fruitful use of our time.

 

We believe we provided the correct solution in our PRACTICAL DATABASE FOUNDATIONS paper #8, The Final NULL in the Coffin. Several reactions to it and our replies are in the queue for posting and they will further clarify and reinforce our position.

 

Ed. Note: We hold the same opinion on anything having to do with objects in database management (as distinct from application development and programming).
