to know the meaning of synchronous and asynchronous
processing and also the meaning of synchronous and
asynchronous database update.

Answer Posted / praveenkumar lingutla

In synchronous processing the transaction is done by one after another and it depend on previous transaction.

In the Asynchronous processing all the transactions is done
at a time.

synchronous update if the legacy system have 5 records the 4 records are correct one record i.e, the 3rd record is error then the process is as follows 1st 2nd records are done successfully but 3rd record is so stop the process.

In the asynchronous update the process is not stopped directly it it goes to the data base
