    We are allowed to take an existing data model from the internet

    it needs to have all these:

    • At least one one-many relationship
    • At least one decomposed many-many relationship-show the original many-many relationship
    • At least one recursive relationship
    • At least one one-one relationship
    • An entity with subtyping that has relationships with other entities that involve the super-type and at least one subtype.
    • No less than 8 entities, no more than 10

    i'm finding it very hard to find a data model with a recursive relationship or "An entity with subtyping that has relationships with other entities that involve the super-type and at least one subtype." (i'm not quite sure what that means?)

    could anyone suggest to me what data model i could use or link me to one that has all of these aspects? or perhaps draw me up one? i'd be very grateful!

    Thanks
