Characteristics Of Transaction Processing System

Introduction

A transaction process system (TPS) is an information processing system used in business transactions that involves the collection, retrieval and modification of the entire transaction data. The characteristics of a TPS include rapid processing, reliability, standardization and control access. TPS is also known as transaction processing or real-time processing.

A transaction process system is often distinguished with a batch processing that most requests are accomplish at one time. The former require the interaction of a user or needs the user to be in attendance. The results of transaction processing system for each transaction are immediately available and there is no delay. To accomplish the performance, reliability and consistency,

When the users book a ticket and select the seat, that booking will be made right away and nobody else can reserve or get the same seat even a second later. Any changes you make to your reservation are also updated in real time. Another example is the stock market. When the user submit an order in buying a stock, that order will be process immediately and not at the end of the day.

In many situations the primary factor is speed. For example, when a bank customer withdraws a sum of money from the account it is very important for the transaction to be processed immediately and the account balance updated as soon as possible to allow both the bank and customer to keep track of funds.

Real-time processing is frequently more efficient and in some cases necessary, batch processing could be more effective. In the case of a payroll system, there is no need to keep the track of how much an employee have earned every minute of the day and doing this every two weeks is likely enough.

Functions of the information system

There are four function main of TPS to accomplish their goal which is input function, storage function, processing function and output

This will involve only one person to performing the functions. If the two separate functions were performed by different people, the existence of two separate transaction processing computer systems, operated at two different terminals was not seen as a problem. A transaction processing system makes it easier for users around the world to use the business's services through a simple online system. The entire characteristic such as rapid processing, reliability, standardization and control access is very important in transaction processing system to become more effective to the users. Real-time processing is frequently more efficient and in some cases necessary, batch processing could be more effective. References
