Do You Need a Data Base?

I think for me, a personal check would be, if you don't know exactly what hapened, where to find something, like the click mind. If it's any note, i open up obsidion, which is always on my convete and or on my phone. An if i want to ave a look at my calendar, i go or see, and then morgan pops up, and then i can se what's going on. It's already on my cam. It's popped up right now. I i know exactly where to go and find things. And that was the thing about notion, where do i put it? Do i need a data base?
