hi. I think the "X" and "-" mean in this matrix [0] is not very intuitive. mainly because "X" tends to mean negative things in most cases. we can write a sentence saying "X" means this, "-" means that.
or maybe Check mark [1] and Cross mark [2] are more universal. and we can use these marks. "Only for local objects" is there any reference explaining "local objects"? I think local object means objects that only affect one single database?
