* Declares which DB operations should be performed within a transaction in different scenarios.

* By default, these methods are NOT enclosed in a DB transaction.
*
* In some scenarios, to ensure data consistency, you may want to enclose some or all of them

* return array(

* The above declaration specifies that in the "admin" scenario, the insert operation ([[insert()]])
* should be done in a transaction; and in the "api" scenario, all the operations should be done
