Explanation

Explanation: An asynchronous operation is one that does not wait for a response before continuing. This allows operations to occur in parallel. Thus, the operation does not block or wait for the response. Asynchronous operations open a communication channel between the parties, make the request, and close the channel before the response occurs. Message correlation is used to relate the inbound message to the outbound message. This method is effective when large numbers of transactions occur that could take long periods of time to process. In the case in which the operations are short or need to run in serial, synchronous operations may be more appropriate. The asynchronous pattern is effective if the end user does not need immediate feedback. Note: A synchronous operation is one that waits for a response before continuing on. This forces operations to occur in a serial order. People often say that an operation blocks or waits for a response. Synchronous operations open a communication channel between the parties, make the request, and leave the channel open until the response occurs. This method is effective unless large numbers of channels are being left open for long periods of time. In this case, asynchronous operations may be more appropriate. Also, the synchronous pattern may not be necessary or appropriate if the end user does not need an immediate response.
