Draw an EER diagram for the following problem and map it into tables: a nonprofit organization depends on a number of different types of persons

Draw an EER diagram for the following problem and map it into tables: a nonprofit organization depends on a number of different types of persons for its successful operation. The organization is interested in the following attributes for all of these persons: SSN, Name, Address, City/State, and Telephone. Three types of persons are of 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 whose strong key is the item#. A donor must have donated one or more items and an item may have 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., employees and donors)
