Explanation

In IMS terminology, a segment type is like a template or structure definition (similar to a class in programming), while a segment occurrence is a specific instance of that type with actual data values (similar to an object). For example, 'CUSTOMER' might be a segment type, while a specific customer's data record would be a segment occurrence. Therefore, segment occurrence is an instance of segment type, not the reverse.
