An entity is a chain of events connected using a common primary key.
Entities help stitch together all critical events associated with a specific business object, in the above-mentioned case, a payment transaction.
The presence/absence of these events helps identify failure points in the transaction.
The attribute values within each event help drill-down and identify variable values within the transactions.
