In batch session interface: - Asynchronous processing means Transfers data for multiple transactions - Synchronous database update means during processing, no transaction is started until the previous transaction has been written to the database.

In CALL TRANSACTION: - Synchronous processing means Transfers data for a single transaction. Synchronous and asynchronous database updating both possible The program specifies which kind of updating is desired. Separate LUW for the transaction The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.

both are use with CALL TRANSACTION METHOD.

In Synchronous process data is updated Record by record

and in Asynchronous process whole data of ceratin transaction is updated in one times means performance degrades..
