I am currently building out an application that will contain many users, two roles and two groups. Logically we want users to be able to be administrators of other users within the two groups.
UserID varchar PK DisplayName Email Role int FK `role`.`RoleID` DATA [jschmo,Joe Schmo,firstname.lastname@example.org,1]
RoleID int PK AI RoleName varchar DATA [1=Master,2=Admin,3=User]
GroupID int PK AI GroupName DATA [1=Marketing,2=Infrastructure]
A user could potentially be an admin of both groups. I don't see the option to multi-select foreign keys but as I understand it, having a comma-delimited list in a column is a bad idea and I should use multiple records but I don't like the idea of having multiple records for each user.
Q: How would I keep track of which groups a user is an admin of?
