public void addMemberToOrganization(Member aMember, Organization anOrganization)

Given: The Member object, member6 and the Organization object, organization45

1. Check if member6 is linked to organization45.
   As member6 is not linked to organization45:
2. organization45 records a reference to member6

If Member is already a member of the organization, do nothing

• Collection<Member> members

• void addMember(Member aMember)

• None

• public void addMemberToOrganization(Member aMember, Organization anOrganization)

• isMemberOf from Organization to Member

Probably could do without the Boolean return and have the UI only allow selection from organizations the member is not already a member of.

Where can an existing Member be selected from within the UI?

The options are:

• From all other Organizations - would need a public method to select all organizations -> all members.
• From all Schools - ditto - all Schools -> all members.
• From everywhere - ditto - Set of both of the above - a bit of a monster.
• Manually by the user picking a school -> Member &/or Organization -> Member.
