Hi, Richard, I'm new here and not really familiar with Appfuse, but it is easy to see that your question has almost no relationship with Appfuse. It's not strange that no one can answer you in short. Actually, I think that your problem should be a general Domain Design problem, and the implementation greatly depends on your knowledge about Hibernate. Maybe you can read some book on those for more help. I'm not good at this, but in my opinion, I think you don't need to make things that complex. You can just define an object: User, and map to USERS table. And all types of users, such as Teacher, Student, they should be modeled as different roles. This is a USER-ROLE many to many model. That is to say, for User class, it contains a roles set, and for the Role class, it contains a users set. User class will map to USERS table, and Role class will map to ROLES table, to link them together, you have another USER_ROLE table contains two columns: user_id, role_id. This table will not map to any class in Hibernate, just used to represent the many to many relationship between user and roles.
Actually this is a general part of the RBAC access control model, if you have any idea of ACEGI (appfuse2 also used this), you should be quite familiar with this. Hope this can give some help.
