What is schedule explain?

A schedule or a timetable, as a basic time-management tool, consists of a list of times at which possible tasks, events, or actions are intended to take place, or of a sequence of events in the chronological order in which such things are intended to take place.

What do you mean by transaction schedule?

Transaction schedule is a sequence of database instructions. A transaction includes read and write database object for executing the actions. In transaction schedules, after finishing the first transaction, the execution of second transaction starts.

Which schedule is strict schedule?

If in a schedule, a transaction is neither allowed to read nor write a data item until the last transaction that has written it is committed or aborted, then such a schedule is called as a Strict Schedule.

What is scheduling in cloud computing?

The concept of scheduling in cloud computing refers to the technique of mapping a set of jobs to a set of virtual machines (VMs) or allocating VMs to run on the available resources in order to fulfill users' demands [4].

What is scheduling and its type?

Schedulers. Schedulers are special system software which handle process scheduling in various ways. Their main task is to select the jobs to be submitted into the system and to decide which process to run. Schedulers are of three types − Long-Term Scheduler.

Why do we need schedule in DBMS?

When multiple transactions are running concurrently then there needs to be a sequence in which the operations are performed because at a time only one operation can be performed on the database. This sequence of operations is known as Schedule.

What are the types of schedules?

The three schedule types are known as the Capacity schedule, Resource schedule, and Service schedule. In some ways, they overlap in what they can do, and for some applications more than one will work.

What is Scheduler and explain its functions in DBMS?

The Scheduler enables database administrators and application developers to control when and where various tasks take place in the database environment. These tasks can be time consuming and complicated, so using the Scheduler can help you to improve the management and planning of these tasks.

What is Cascadeless schedule in DBMS?

Schedules in which transactions read values only after all transactions whose changes they are going to read commit are called cascadeless schedules. Avoids that a single transaction abort leads to a series of transaction rollbacks.

What is concurrent schedule in DBMS?

A schedule is said to be concurrent in case the instructions of the transactions get executed preemptively. When the database system executes several transactions concurrently, the corresponding schedule no longer needs to be serial. ... With multiple transactions, the CPU time is shared among all the transactions.

What is parallel schedule in DBMS?

A schedule is required in a database because when some transactions execute in parallel, they may affect the result of the transaction – means if one transaction is updating the values which the other transaction is accessing, then the order of these two transactions will change the result of second transaction.

What is the use of scheduling?

Scheduling is the art of planning your activities so that you can achieve your goals and priorities in the time you have available. When it's done effectively, it helps you: Understand what you can realistically achieve with your time. Make sure you have enough time for essential tasks.

What is scheduling in embedded system?

The way that time is allocated between tasks is termed “scheduling”. The scheduler is the software that determines which task should be run next. The logic of the scheduler and the mechanism that determines when it should be run is the scheduling algorithm.

Why is scheduling done?

Scheduling is done to balance the load on the system and ensure equal distribution of resources and give some prioritization according to set rules. This ensures that a computer system is able to serve all requests and achieve a certain quality of service. Scheduling is also known as process scheduling.

What is short term scheduling?

Short-term scheduling involves selecting one of the processes from the ready queue and scheduling them for execution. This is done by the short-term scheduler. A scheduling algorithm is used to decide which process will be scheduled for execution next by the short-term scheduler.

What are scheduling methods?

Techniques such as PERT (Program Evaluation and Review Technique), CPM (Critical Path Method) and GANTT are the most used to plan into details a project, prevent uncertainties and avoid risk. ...

What is schedule to an act?

A schedule is a part of an act that contains extra information that has not been written in the body of the legislative document. It is an appendix attached to any act, supplementing the legislation with additional information that is not mentioned under the main text of the articles.
