Mods that have 'Database Changes'

[Kwak]

Major Addition mods require 'DB Changes'
No harm done, I think.


If you add two major additional mods that have 'DB Changes' today, add more mods down the road with 'DB Changes,' is there a chance that the db changes will eventually collide with other changes, causing a fatal error with the forum?

Or does each mod add new database and changes its own database?

Explanation on the database is appreciated.
