Remember when Rational Rose was a thing that was going to make programming obsolete? I spent six months of my career writing insanely detailed UMLs for a future that never arrived
I do study the olde days pretty heavily (because it's true this stuff is cyclical and we shouldn't treat it like pop culture) but I only dimly knew about that phase enough that it rang a bell once people reminded me today
Do you recognize Together/J ?
"Together/J is a UML modeling tool that provides the ability to simultaneously draw UML diagrams and generate the corresponding Java code."
