       | As for Date, he is a gem:
       | 
       |  _" Thank you for saying my writing style is "coherent"! But I
       | think I can explain that, too. The truth is, I'm a rather slow
       | learner. As a consequence, I think I can be a good teacher,
       | because I can identify places where students are likely to have
       | trouble._"
       | 
       | I have learned so much from him.

       | 
       | What I mean: the relational model has replaced existing
       | hierarchical models. Isn't that proof by practice that the
       | underlying mathematical model (set theory, predicate logic) is
       | extraordinarily well suited to cover data structuring and
       | information modeling in computer science. And, yes, hierarchies
       | are also first-class citizens in relational models and can scale
       | beautiful.
       | 
       | Even the developments, yes, "hypes" of recent years and decades
       | such as NoSQL or knowledge graphs and graph databases have not
       | fundamentally shaken this, but we are increasingly seeing a
       | return to the proven relational model. Hence "history repeating".
