Hi Deepthi,
I have never worked with MDM, but i dont understand the term "Asynchronous System". As far as i know MDM is developed in the SAP Netweaver platform, then you can develop a Z RFC or inbound proxy in order to make a synchronous communication. Inside this Z code you can store the data in Z tables or interact with the MDM in asynchronous way if you want it.
Regards.
