I’ve been playing with a DB for a personal project, and I want to start again, and sketch out some ideas on how to set it up. I only want a GUI that I can set up tables and connect them together and set their properties. Maybe add notes.
Just a simple UI tool. I don’t want it to access my db or whatever, I just want to sketch it out. What do you use for DB planning?


Seconding draw.io as the swiss-army-knife that’ll do this and more…
But honorable mention to graphviz if you want dead-simple, low-friction charts: https://zackees.github.io/webgraphviz/
