Draw an EER diagram for the following problem using this textbook’s notation.  [Note from Beckman: the textbook notation is what we used in class; do not use the “Visio” notation or the “subtypes inside supertypes” notation.]A nonprofit organization depends on various distinct types of persons for its successful operation.  The organization is interested in the following attributes for all these persons: SSN, Name, Address, City/State/Zip, and Telephone.  Three types of persons are of the greatest interest: employees, volunteers, and donors.  Employees have only a Date Hired attribute, and volunteers have only a Skill attribute.  Donors have only a relationship (named Donates) with an Item entity type.  A donor must have donated one or more items, and an item may have no donors or one or more donors.There are persons other than employees, volunteers, and donors who are of interest to the organization so that a person need not belong to any of these three groups.  On the other hand, at a given time a person may belong to two or more of these groups (e.g., employee and donor).
