Detailed explanation-1: -Such queries require a lot of processing time to execute. By executing these queries in parallel, you can reduce the elapsed time while still providing the required processor time. Speedup is defined as the ratio between the runtime with one processor and the runtime using multiple processors.
Detailed explanation-2: -The Database Management System (DBMS) is defined as a software system that allows the user to define, create and maintain the database and provide control access to the data.
