The Link-base class is an abstract class that is an ancestor class to other classes that identifies paired object instances in your system.

For example, the Link-Attachment class records the date, time, Operator ID, and other facts about an attachment and a work object. While each instance defines only one pair association, the overall relationship between linked objects can be many-to-many.

In contrast to Index- classes, the Link- classes record overt input from users or from other systems, and are not primarily defined to speed searches or retrieval.

These classes and their instances are visible through the Class Explorer.
