Question

Discuss Batch Processing System. The Strengths and weaknesses of the batch processing system. Six (6) documents used in the Batch Processing System. Any way the batch processing system will improve the operation of the Payroll Unit  

Answer 1

Batch processing is the processing of transactions in a group or batch. No user interaction is required once batch processing is underway. This differentiates batch processing from transaction processing, which involves processing transactions one at a time and requires user interaction.

While batch processing can be carried out at any time, it is particularly suited to end-of-cycle processing, such as for processing a bank's reports at the end of a day or generating monthly or biweekly payrolls.

atch processing is a technique in which an Operating System collects the programs and data together in a batch before processing starts. An operating system does the following activities related to batch processing − The OS defines a job which has predefined sequence of commands, programs and data as a single unit.

Advantages of Batch Processing System

• In batch system all jobs are performed in repeating form without user’s permission.

• Can be feed input data in the batch processing system without using extra hardware components.

• Small scale business can use batch processing system for executing small tasks to their benefits.

• For giving rest to system’s processors, your batch system is capable to work in off-line mode.

• Batch processing system consumes less time for executing the all jobs.

• Batch system is shareable nature, so it can be shared for couples of users, if needed.

• When batch processing system executes their jobs then its idle time is very low.

• Batch processing system has more capable to handle huge repeated task smoothly.

Disadvantages Batch Processing System

• Provide well education to computer handler for operating the batch processing system.

• It takes more time for debugging the batch processing system.

• Some time it may be more costly.

• It has more turnaround time.

• It has Non linear behavior.

• Model inaccuracies.

• Batch processing system’s online sensors is often not available.

• Include constrained operation.

• Unmeasured disturbances.

• Irreversible behavior.

• Time-varying process characteristics.

• If any one job halts, then increase workload for predicting time.

• Due to any mistake, any job can enter into infinite loop.

• If your protection system is not well then, any one job can affect pending jobs.

Batch processing is appropriate for making payrolls. The statements are made easy to process while using the batch systems. In batch systems, repeated jobs are done fast. No need for additional hardware and system support to input data

Mainframes working after hours: Batch processing. Batch applications are processed on the mainframe without user interaction. A batch job is submitted on the computer; the job reads and processes data in bulk— perhaps terabytes of data— and produces output, such as customer billing statements.
