Batch processing Batch processing is execution of a series of programs jobs on a computer without manual intervention.

Several transactions, called a batch are collected and processed at the same time. The results of each transaction are not immediately available when the transaction is being entered; [1] there is a time delay.

Transaction processing - Wikipedia

Real-time computing "Real time systems attempt to guarantee an appropriate response to a stimulus or request quickly enough to affect the conditions that caused the stimulus. Transaction processing A Transaction Processing System TPS is a type of information system that collects, stores, modifies and retrieves the data transactions of an enterprise.

Transaction processing systems also attempt to provide predictable response times to requests, although this is not as critical as for real-time systems.

Rather than allowing the user to run arbitrary programs as time-sharing, transaction processing allows only predefined, structured transactions. Each transaction is usually short duration and the processing activity for each transaction is programmed in advance.

Transaction processing system features[ edit ] The following features are considered important in evaluating transaction processing systems. Transaction processing systems are usually measured by the number of transactions they can process in a given period of time.

Continuous availability[ edit ] The system must be available during the time period when the users are entering transactions. Many organizations rely heavily on their TPS; a breakdown will disrupt operations or even stop the business. Data integrity[ edit ] The system must be able to handle hardware or software problems without corrupting data.

Multiple users must be protected from attempting to change the same piece of data at the same time, for example two operators cannot sell the same seat on an airplane. Ease of use[ edit ] Often users of transaction processing systems are casual users.

The system should be simple for them to understand, protect them from data-entry errors as much as possible, and allow them to easily correct their errors. Modular growth[ edit ] The system should be capable of growth at incremental costs, rather than requiring a complete replacement.

It should be possible to add, replace, or update hardware and software components without shutting down the system.

Types of transaction processing[ edit ] Processing in a batch[ edit ] Transactions may be collected and processed as in batch processing. Historically, this was the most common method as the information technology did not exist to allow real-time processing.

Best practice reconciliation procedure A transaction process system TPS is an information processing system for business transactions involving the collection, modification and retrieval of all transaction data.

What is a Transaction Process System (TPS)? - Definition from Techopedia Information System 3 2.

Processing in real-time[ edit ] This is the immediate processing of data. It provides instant confirmation of a transaction. It may involve a large number of users who are simultaneously performing transactions which change data.

Because of advances in technology such as the increase in the speed of data transmission and larger bandwidthreal-time updating is possible. Databases for transaction processing[ edit ] Main article: Database A database is an organized collection of data.

Databases offer fast retrieval times for non-structured requests as in a typical transaction processing application. Databases for transaction processing may be constructed using hierarchical, network, or relational structures. Its top-to-bottom-like structure consists of nodes and branches; each child node has branches and is only linked to one higher level parent node.

But, unlike hierarchical, each child node can be linked to multiple, higher parent nodes. This gives flexibility as relationships between the tables are built.

The following features are desirable in a database system used in transaction processing systems: The database should be designed to access patterns of data from many simultaneous users. Short transactions enables quick processing.

This avoids concurrency and paces the systems. Backup should be scheduled between low times of activity to prevent lag of the server. This lowers redundant information to increase the speed and improve concurrency, this also improves backups. Archiving of historical data: Uncommonly used data are moved into other databases or backed up tables.Transaction Processing Applications A transaction processing application is a collection of transaction programs designed to do the functions necessary to automate a given business activity.

The first on-line transaction processing application to receive widespread use was an airline reservation system: the SABRE system developed in the early. Transaction processing is designed to maintain a system's Integrity (typically a database or some modern filesystems) in a known, consistent state, by ensuring that interdependent operations on the system are either all completed successfully or all canceled successfully.
