Object databases routinely go away and routinely come back.

Ten years ago I worked with a database called Versant OODBMS (from Actian). I was a junior sysadmin so i was essentially administering it at a very surface level but skimming the documentation (and trying some of the samples) it was very cool that you could pick essentially any random class, implement an interface (and hence a few method) and that was it, you had a database-serializable object.

The main issue was really scaling out (as in, multiple machines) but otherwise was a really great database.

Yes, POET for C++, for example.

That's funny, one of my buddies from college was one of the OG Versant employees (I assume there's not another OODBMS named Versant). That was in the late 80s.

Cool! I used Versant at work between 2016 and 2019!
