Abstract:
Query Optimization is to use the best plan for the query that improves the performance of the query. Query Optimization is difficult in distributed databases as compared to centralized databases. Queries in distributed databases are effected by factors such as insertion methods of the data into the remote server and transmission time between servers. Response time of the query depends upon the transmission time, local processing speed.
