We are planing to develop an application with Amazon Dynamo db. Actually this application is collecting information from my client's database(my client's are using MYSQL, Oracle,MSsql/ any other Relational database), doing some process in my application and send back results to the client's database. This synchronization process should work always(or every 1 minute interval).
I want to know is there any tools(or tricks) are available for synchronization between Amazon dynamo database and Relational database?
