The nested transaction programming model addresses the transaction composability problem by capturing the program-subprogram structure of an application within the transaction structure itself.

Spring nested transactions are a bit like the black sheep of the transaction family - easily misunderstood and cast aside in documentation. Nested transactions are however incredibly useful...

The article reviews nested transactions in SQL Server and provides particular examples with outer and inner transactions that may help to handle errors.
