Types of database architectures

A Database Architecture represents the Database Management System’s (DBMS) design (schema). The DBMS architecture makes it easy to understand the components involved in the database system and their relations. The DBMS architecture may vary based on the system on which it runs. Some systems contain both client and server machines whereas some run only on a server machine. Based on the architecture, the system can be classified as centralized, decentralized, or hierarchical.

Deadlock of two processes 3. We see two processes PO and P1 can be in deadlock caused by two semaphores S and Q like below: Let S and Q be two semaphores initialized to 1 Po wait (S); wait (Q) ; signal (S); signal (Q) ; P₁ wait(0); wait (S); signal (Q) ; signal (S); (a) Explain why this happens, i.e. PO waiting for P1 to release something, while P1 waiting for PO to release another thing. (b) Can this be fixed by changing the order of some instructions of P1? Explain!
(b) Consider the following solution to the critical-section problem of two-processes: turn:= 0, busy := false Pi: init-i while(true){ while (turn != i) { while(busy) turn := i } busy := true } crit-i busy :=false rem-i } For the following question either provide a proof, or show an execution where it fails. Explain whether the above code meets all requirements for mutual exclusion.
Please use P and V operations to solve the following problem. There are two processes P0 and P1. P0 and P1 share a variable balance. Suppose that we enforce the order of the following events: P0 does some computation, and then updates the value of balance; P1 reads the value of balance, and does some computation. That is, P1 can only read the value of balance after P0 updates the value of balance.
Consider the following set of processes, with the length of the CPU-burst time given in milliseconds: In addition to the processes listed above, the system also can enter an idle state (which there is no consumption for CPU resources. This idle state identified as p_idle). This state should be appearing in drawing Gantt Chart whenever the system has no other available processes to run. Each process is assigned a numerical priority, with a higher number indicating a higher relative priority. For each of the scheduling algorithms: FCFS (first come, first serve) Preemptive, Round robin scheduling algorithm: The length of a time quantum is 10 units. If a process is preempted by a higher-priority process, the preempted process is placed at the end of the queue. Draw a Gantt chart to show how these processes would be scheduled. Give the turnaround time (total time from first arrival into ready state until cpu-burst is completed) of each process. Give the waiting time (total time spent…
n processes are time-sharing the CPU. The average total CPU time is T. The time quantum is Q. The context switching overhead is S.

We have 4 periodical processes II₁, II, II and II, that process a video. We know their periods P; and their running times C; (in milliseconds). For: (a) the rate monotonic scheduling (RMS) algorithm and (b) the earliest deadline first (EDF) algorithm draw diagrams that displays the schedule for those processes for a period of 150 ms. The times are the following: Process Pi Ci II₁ 45 10 II2 40 10 II3 35 5 II4 50 10 In the case of equal priorities the process that is already running has the priority. If this is not the case then take the process with the lowest ID. Does any of the above algorithms fail?
Consider a system where processes can be dynamically created or terminated. A process can generate a new process. For example, Pi generates both P₂ and P3. Modify the happened-before relation and the linear logical clock scheme for events in such a dynamic set of processes.
“Priority inversion is a condition that occurs in real time systems where a low priority process is starvedbecause higher priority processes have gained hold of the CPU”- Comment on this statement.
Suppose that an operating system supports two kinds of sequential processes: high-priority interactive processes, and low-priority non-interactive processes. The behavior of the high-priority processes is to alternate between periods of computation of duration Tc and periods of blocking (waiting for input) of duration Tb. The behavior of the low-priority processes is to compute constantly, with no blocking. The operating system’s scheduling policy is round-robin with a quantum q, where Tc < q. Scheduling decisions are made only when a quantum expires, or when the running process blocks. The scheduler selects a low-priority process to run only if no high-priority processes are ready. Suppose there is one high-priority process and one low-priority process in the system, and that both processes will run for a long time. For what fraction of the time does the low-priority process run?
Let the processes P1, P2, P3, and P4 be given. They arrive in the system at the same time in this order. The processes have the following service times (in time units): Process Service time (CPU burst) exe P1 53 und P2 17 P3 68 P4 all 24 ur ca ulations. TOU arts. For the scheduling method "Round Robin" (RR), specify the average execution time (average turnaround time) and the number of context switches. The time quantum q is set to 20 time units. You must show your calculations. You will not have to draw Gantt charts. Note: For RR, processes execute in order of their ID (i.e., P1-P2-P3-P4).
