A college course may have one or more scheduled sections, or may not have a scheduled section. Attributes of Course include courseID, courseName, and units. Attributes of Section include sectionNbr and semester. The value of sectionNbr is an integer, which distinguished one section from another for the same course, but does not uniquely identify a section. There is an operation called findNumSections, which finds the number of sections offered for a given course in a given semester.

A large retail organization previously divided work among its four employee-benefits staff into distinct specializations. One person answered all questions about superannuation (pension plans), another answered all questions about various forms of paid time-off (e. g., vacations), and so on. These jobs were recently restructured so that each employee-benefits person answers all questions for people in a particular geographic area. One staff member is responsible for all employee-benefits inquiries from anyone in a particular geographic region.
