Each Decision Service call is one database transaction. Transactions are not per operation, per Rulesheet, or per Ruleflow. Corticon does not currently provide for configuration of transaction management.

The default transaction isolation level in Corticon EDC is the same as the default transaction isolation level of the database to which it is connected.

When an exception occurs, the database transaction is rolled back, and the database reverts to the same state as before the Decision Service was called.
