Concurrency Control

The simultaneous occurrence of two or more operations is called concurrence and the situation is called concurrency. In concurrency, the function of one operation can affect the function of the other and put data integrity at risk. Hence, management for the control of concurrency is required. The management or controlling system in the Database Management System (DBMS) that coordinates concurrent access is called the concurrency control system.

You are designing a real-time system that must execute the following set of processes: P1(20,3); P2(5,2); P3(350,15); P4(500,22); P5(100,10) Note: The first parameter listed for each process is the period, and the second is the maximum execution time. Can these processes be scheduled using Rate Monotonic? You must justify your answer. Can these processes be scheduled using Earliest Deadline First? You must justify your answer. If possible, identify the simplest of these strategies that can be used to schedule these processes.
