Method and device for hierarchically and asynchronously processing transactions

The embodiment of the invention provides a method and device for hierarchically and asynchronously processing transactions. The method comprises the steps of dividing a transaction into a plurality ofsubtasks according to an internal business logic relationship of the transaction, marking the subtasks which have priority processing marks and need to be processed in advance according to the internal business logic relationship, and marking other subtasks in a rear queue; executing the sub-tasks in the front queue of the transaction; according to the internal business logic relationship of thetransaction, transmitting parameters generated by executing the sub-tasks in the front queue to other associated sub-tasks; after the sub-tasks in the front queue are processed, executing the sub-tasks in the rear queue of the transaction; and feeding back and displaying execution results of all sub-tasks of the transaction. And the sub-tasks with high importance can be executed preferentially, sothat the processing period
