Outline Abstract VIRTUAL DATABASE SYSTEM IMPLEMENTATION OF VIRTUAL DATABASE WITH HADOOP MAPREDUCE QUERY OPTIMIZATION

Abstract proposes to utilize the parallel and distributed processing capability of Hadoop MapReduce for handling heterogeneous query execution on large datasets.

VIRTUAL DATABASE SYSTEM Publisher Mapper Executor Wrapper Metadata

VIRTUAL DATABASE SYSTEM

IMPLEMENTATION OF VIRTUAL DATABASE WITH HADOOP MAPREDUCE

QUERY OPTIMIZATION Removes the grouped queries from this queue and Processes using different workers. This effectively optimizes the time spent in Processing and executing duplicate queries.
