TPS is also known as transaction processing or real-time processing. A few of these critical features are described below. The four important characteristics include, -Turnaround time from transaction input to the production output must be a few seconds or less, -If failure occurs, recovery must be quick and accurate, -Every transaction must be processed in the same way, -Flexibility results in too many opportunities for non standard operations, resulting in problems due to different transaction data, -Must support an organisation's operations, -If roles and responsibilities are allocated, the TPS should maintain these requirements, -TPS systems reduce costs by reducing number of times data must be handled, -Collects the transaction data as a group and processes it later, -Used for pay cheques and when a time delay does not decrease the usefulness of the results, Errors cannot be corrected during processing, Sorting the data is expensive and time consuming, -Instant confirmation of a transaction but does require access to an online database, -Uses a terminal or workstation to enter data and display the results of the TPS, -A network links terminals to mainframe computer, -large number of users simultaneously perform transactions(requests are also simultaneous), Concurrency: Two users cannot change the same data at the same time, E.g if an airline agent has reserved the last seat, another agent cannot tell another passenger that seat is available, Atomicity: all steps involved in a transaction are completed successfully, -if any steps fail no other should be completed, -E.g transferring money between accounts(the withdrawal must succeed for the transfer to succeed), -The response time delay must be acceptable for the application to be considered real time, -Main disadvantage=expense, due to hardware and software, -Software that allows the transaction processing application programs to run efficiently, -Provides standard interface between input devices, programs and DBMS, -Ensures transactions do not get lost or corrupted, Real time requires more availability of master file for updating and referencing, Real time has fewer errors, as in batch the data is organised and stored before updating, Infrequent, yet tolerable, errors can occur in batch, More computers are required in real time processing, More difficult to maintain a real time system, -Used to check the entry of transaction data to ensure the transactions are correct and have been accurately stored in the database, Transaction initiation: Used to acknowledge that the TP monitor is ready to receive the transaction data. ssing have fewer errors than batch processing? Examples of transaction processing systems, 5. It should understand this as a transaction processing cycle of several basic activities . Input must become output in seconds so customers don’t wait. collect, store, modify and retrieve the transactions, -TPS must be designed to specifically fit the businesses needs. 5) List three disadvantages of batch processing. There are several features involved in a good transaction processing system. TPS, a cross-functional information system were among the earliest computerized systems developed to record, process, validate, and store business for future use or retrieval. batch processing. 2. RAPID RESPONSE- Fast performance with a rapid response is critical. 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.
