Today managing data is very critical for all kind of users. Some users use Cloud Database Services for managing their data but at the same time for the security reasons they want to keep some crucial private data at their own end so they face problem like how to integrate both kind of data one located at Local RDBMS and the other at Cloud repositories. In this paper we have analyzed that Hadoop can be used to solve such kind of problems. Hadoop platform is used to integrate data one is located at the Cloud databases and the other located at the Local RDBMS. Hadoop components not only process huge amount of data but with the help of inbuilt security mechanisms one can also securely store their data.
