Output can be printed on paper (hard copy) or displayed on the screen (soft copy). ВЁDocument Production is the process of creating reports and outputting records. ВЁData Storage is the process of placing transaction data into one or more databases. ВЁData Manipulation is the process of performing calculations and other data transformations like classifying data and sorting files. ВЁData Correction is the process of reentering mis-keyed or mis-scanned data that was found during the data editing. ВЁData Editing is the process of checking data for validity and completeness. Can be done manually, or using devices like scanners and point-of-sale equipment. ВЁData Collection is the process of capturing and gathering all data needed to complete one or more transactions. The following is a simple activity diagram illustrating the basic structure of typical transaction processing systems. * reports are designed to give management an overview of the transactions performed, and are often used for decision making purposesД«asic structure of transaction processing systems * controls ensure the systems objectives are properly met, for example, that the data integrity meets minimum standards

Other key features of transaction processing systems include controls and reports: * another example is the transferring of data entry to the customers of the organisation - bank customers using automatic teller machines are effectively doing the data entry for the bank many Internet/e-commerce based applications are using the customers for data entry Without these, it can often be uneconomic to capture this data * one example is the use of bar codes - these speed up data capture and make it much more reliable. This generally meant that these early transaction processing systems were co-located on one large central mainframe.ДЄ key feature of most of these systems are the methods used to streamline the processing: Grosch's Law claimed that computing power was proportional to the square of the cost of the processor - this favoured ever larger centralised mainframes over smaller distributed systems. * few other business processes within typical organisations could provide these benefitsДЄt this point, it is also worth noting that centralised systems were initially easier to control and could achieve economies of scale. * small savings in the costs to process large numbers of transactions added up to significant amounts that would cover the costs of the expensive equipment * these systems were among the easier to create * computer equipment was relatively expensive in these early days Typically, transaction processing business processes were among the first to be automated/computerised in most organisations, thus a lot of this early work with this type of system provides the foundation for current thinking about information systems. ВЁMaintain error-free data input and processing ВЁCapture, process and store transactions and produce output They often involve multiple steps, but if any of the steps fail then the whole transaction cannot proceedДЄnalysing transaction patterns and volumes of transaction data is an important middle management activity in any business process. Transaction processing is often the core of most major activities in organisations and the systems that collect this data often support other systems that might be decision support, management information or executive information.ДЄ transaction is a fundamental unit of activity in organisations and are generally indivisible. For most organizations, the TPS is the basis of the day-to-day activities that occur in the normal course of business, adding value to its products or services.

Most TPSs consist of all the components of a CBIS including databases, telecommunications, people, procedures, software and hardware. A Transaction Processing System (TPS) is an organized collection of people, procedures, databases, hardware and software to record completed business transactions. Most individual transactions are relatively simple, but in most organisations, there are very large numbers of them - so speed and efficiency are important considerations.ДЄ transaction is any business-related exchange such as a payment to an employee, a sale to a customer, and a payment to a supplier. * others involve recording or retrieving data (making a booking, enrolling a student at university looking up results etc)

* some are commercial transactions (buying, selling products and services, paying bills etc) Transactions are the routine day-to-day activities performed by most organisations.
