A relationship family corresponds to a database table that is used to relate two entity family tables. Relationship definitions specify which entity families can be connected through that relationship for a given relationship family. A link is a relationship family record that stores the information relating two entity family records.
Consider an example where the Has Maintenance relationship family relates the Compressor entity family to the Work Order entity family. If a Compressor record exists in the database to identify a specific piece of equipment and you create a Work Order record to store the information associated with the maintenance that was performed on that piece of equipment, you might want to relate the two entity family records to one another. You would do so by creating a link between the two entity family records.
When you link two entity family records together, GE Digital APM creates a record in the appropriate relationship family table. The relationship family record, or link, contains:
The link may also contain other data if additional fields have been defined for the relationship family.
