Hi m8
I am far from sql literate but from what i gather new hacks/mods either create new colums/sections whatever ya want to call them in the specific sections of the database,
They can also add on some of the existing sections as well
e.g. the USERS section of the database has numerous sections/colums and if the section coloum that is not there they will add the section such as a points system, this will have its own little part in the USERS section of the database....
As far as i am aware nothing drastic ever really happens if theres a conflict, perhaps the odd sql error and usuall if you go back to the coder where you got the hack from they will either fix the error (conflict) or point you in the direction of the previous coder that thier hack is conflicting with, either way the majority of the time there is a fix....
Does this make sense to you...caus eit dont to me, it just sounded good as i was typing it
I am sure some one else can explain it better than me but mine is a=in laymans terms though
