Batch Processing
Batch Processing
Batch processing is a computer process where multiple tasks are grouped together and processed as a single unit to improve efficiency and reduce processing time. It involves collecting data and executing it in large quantities without user intervention.
What does Batch Processing mean?
Batch processing is a data processing technique that involves accumulating transactions or data over a period of time and processing them in a single batch. This approach differs from real-time processing, where data is processed as it is received, and interactive processing, where the user interacts with the system during processing.
Batch processing systems typically have three main stages:
- Batch Creation: Transactions or data are collected and accumulated into a batch.
- Batch Processing: The batch is processed as a whole, applying consistent rules and logic to all items in the batch.
- Output Generation: The results of the processing, such as reports, updates, or summaries, are generated and made available.
Applications
Batch processing is a critical component of many technology systems, including:
- Data Warehousing: ETL (Extract, Transform, Load) processes for data warehousing systems are often performed in batches to improve efficiency.
- Financial Processing: Billing systems, such as utility bills or credit card statements, are typically processed in batches.
- Manufacturing and Logistics: Inventory control, production Scheduling, and Supply Chain Management systems rely on batch processing for data aggregation and analysis.
- Scientific Computing: Large-scale simulations and data analysis tasks can be processed efficiently in batches.
- Blockchain Technology: Batching transactions and blocks in blockchain networks helps to improve scalability and security.
History
The concept of batch processing emerged in the early days of computing, with the introduction of punch cards as a data storage medium. These cards were loaded into computers in batches and processed in sequence.
In the 1950s, batch processing systems became widely adopted for business applications, such as payroll processing and inventory management. The development of mainframe computers provided the necessary computing power and storage Capacity to handle large batches of data.
Over time, batch processing systems evolved with advances in hardware and software technology. The introduction of magnetic tape and disk storage devices made it possible to process larger batches and store data for extended periods. The development of database management systems facilitated the management and organization of data within batch processing systems.
