directly publishes data changes to a message solution instead of transmitting these changes to an already registered node. This router must be manually configured as an extensibility point in XML format. (Can be combined with Kafka, then data can be entered into the Hadoop ecosystem)7. Audit Table Router: This Router inserts data into an automatically created audit table. The data captured by this router record changes to the table associated with it.Trigger and router are many-to-many relation
