Question: Large transaction processing systems in automated organisations use

Answer:

Batch processing is a method of data processing where a group of transactions or data records is collected over a period of time and processed together as a batch. In batch processing, data is typically processed without user interaction or in real-time, and the processing occurs in a sequential manner.

Here are some key characteristics and benefits of batch processing:

1. Collection of Data: Batch processing involves collecting a set of data or transactions over a period of time. This data can be collected from various sources, such as databases, files, or external systems.

2. Processing in Batches: Once a sufficient amount of data is gathered, it is processed as a batch. The batch can contain multiple transactions or records that are processed together.

3. Scheduled Execution: Batch processing is often scheduled to run at specific times or intervals, such as overnight or during periods of low system activity. This allows organizations to make the most efficient use of computing resources and minimize disruption to regular business operations.

4. No User Interaction: Batch processing is typically automated and does not require user interaction during the processing phase. It allows for the efficient handling of large volumes of data without manual intervention.

5. Sequential Processing: Batch processing follows a sequential order, where each transaction or record in the batch is processed one after another. This approach simplifies the programming and ensures the order and integrity of the processed data.

6. Resource Optimization: Batch processing can optimize system resources by processing a large amount of data in a single batch. It reduces overhead associated with transaction initiation, communication, and context switching between tasks.

7. Error Handling: Batch processing includes error handling mechanisms to handle exceptions or errors that may occur during the processing. Error records can be logged or processed separately for manual intervention or further investigation.

Batch processing is commonly used in various industries and applications, such as billing systems, payroll processing, data analysis, report generation, and large-scale data transformations. It allows organizations to efficiently process and manage high volumes of data in a controlled and automated manner.
