The Group data in the Issue Listing page and in Advanced Search page - something I totally
missed out. I really need to rethink by considering this.
Thanks for point that out.

I would agree in that Groups should just be a many-to-many relationship
with user and that having a primary group would just add unnecessary
Obviously the functions handling groups would have to return arrays
however we also need to consider the functions calling the group
functions also have to be able to handle the returned arrays. It is not
just 'backend engines' that use group - the main issue listing screen
has a filter by group which will need careful changes made to ensure
that screen still works correctly.
I would say that assignment of an issue should still be to the one group
rather than to many.

My two cents would be to try to avoid the 'primary group' idea. Though
it may be more coding (or maybe not - I wouldn't be surprised if a
primary group structure actually made things harder) I think it will be
a lot more logical a shift if the group column is completely removed
from the user and all group operations lookup against the user_group
table. This would mean
getGroupID() returns an array (and preferably is renamed getGroupIDs()
or something similar). setGroupID() would give way to addGroupID() and
removeGroupID() and while I don't know what getActiveAssocList() it
similarly would be revamped to handle multiple groups per person.
Additionally, I'm not sure why you need an id column for the
many-to-many user_group table. Simply creating a unique index on the
two columns should be enough - I think. If there's a good reason I'm
wrong, feel free to correct me, but in the past I haven't needed an id
for many-to-many tables.
