As a large service organization, King Abdullh University Hospital depends on a large number of persons for its continued success. There are four groups of persons on whom the hospital is most dependent: employees, physicians, patients, and volunteers. Of course some common attributes are shared by all of these persons: Person_ID (identifier), Name, Address, Ciy/State/Zip, Birth_Date, and Phone.Each of the four groups of persons has at least one unique attribute of its own. Employees have a Date_Hired, Volunteers have a Skill, Physicians have a Specialty and a Pager# (pager number), and Patients have a Contact_Date (date of first contact with the hospital).Some other persons in the hospital community do not belong to one of these four groups (their numbers are relatively small). However, a particular person may belong to two (or more) of these groups at a given time (for example, Patient and Volunteer).Each patient has one (and one only) physician responsible for that patient. A given physician may not be responsible for a patient at a given time or may be responsible for one or more patients. Patients are divided into two groups: resident and outpatient. Each resident patient has a Date_Admitted attribute. Each outpatient is scheduled for zero or more visits. The entity visit has two attributes: Date (partial identifier) and Comments. Notice that an instance of visit cannot exist without an outpatient owner entity.Employees are sub-divided into three groups: nurse, staff, and technician. Only nurse has the attribute Certificate, which indicates the qualification (RN, LPN, etc.). Only staff has the attribute Job_Class, and only technician has the attribute Skill. Each nurse is assigned to one (and only one) care center. Examples of care center are Maternity, Emergency, and Cardiology (care centers were formerly called wards). Attributes of care center are Name (identifier) and Location. A care center may have one or more nurses assigned to it. Also for each care center, one of the nurses assigned to that care center is appointed nurse-in-charge. A nurse cannot be appointed nurse-in-charge of a care center unless she or he has an RN certificate.Each technician is assigned to one or more laboratories. Attributes of laboratory include Name (identifier) and Location. A laboratory must have at least one technician assigned to it and may have any number of technicians assigned.There may be no beds assigned to a care center, or a care center may have one or more beds (up to any number) assigned to it. The only attribute of bed is Bed_ID (identifier). Bed_ID is a composite attribute, with components Bed# and Room#. Each resident patient must be assigned to a bed.

As a large service organization, King Abdullh University Hospital depends on a large number of persons for its continued success. There are four groups of persons on whom the hospital is most dependent: employees, physicians, patients, and volunteers. Of course some common attributes are shared by all of these persons: Person_ID (identifier), Name, Address, Ciy/State/Zip, Birth_Date, and Phone. Each of the four groups of persons has at least one unique attribute of its own. Employees have a Date_Hired, Volunteers have a Skill, Physicians have a Specialty and a Pager# (pager number), and Patients have a Contact_Date (date of first contact with the hospital). Some other persons in the hospital community do not belong to one of these four groups (their numbers are relatively small). However, a particular person may belong to two (or more) of these groups at a given time (for example, Patient and Volunteer). Each patient has one (and one only) physician responsible for that patient. A given physician may not be responsible for a patient at a given time or may be responsible for one or more patients. Patients are divided into two groups: resident and outpatient. Each resident patient has a Date_Admitted attribute. Each outpatient is scheduled for zero or more visits. The entity visit has two attributes: Date (partial identifier) and Comments. Notice that an instance of visit cannot exist without an outpatient owner entity. Employees are sub-divided into three groups: nurse, staff, and technician. Only nurse has the attribute Certificate, which indicates the qualification (RN, LPN, etc.). Only staff has the attribute Job_Class, and only technician has the attribute Skill. Each nurse is assigned to one (and only one) care center. Examples of care center are Maternity, Emergency, and Cardiology (care centers were formerly called wards). Attributes of care center are Name (identifier) and Location. A care center may have one or more nurses assigned to it. Also for each care center, one of the nurses assigned to that care center is appointed nurse-in-charge. A nurse cannot be appointed nurse-in-charge of a care center unless she or he has an RN certificate. Each technician is assigned to one or more laboratories. Attributes of laboratory include Name (identifier) and Location. A laboratory must have at least one technician assigned to it and may have any number of technicians assigned. There may be no beds assigned to a care center, or a care center may have one or more beds (up to any number) assigned to it. The only attribute of bed is Bed_ID (identifier).
