| 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".
