Integer Key Sizing
As two of you know, I am proceeding along with my modest yet poweful CMS that loosely couples with vBulletin.
I am seeking some design perspective.
JelSoft chose to implement usergroupid as a smallint(5). I believe that I want to expand that in areas where my system touches vB. Would it be a bad idea to have one table (vB) keyed by usergroupid (smallint-5) and another (my) table keyed by usergroupid (int-11). Any issues with joining the two tables ?
