Characteristics of transaction processing system

A transaction processing system (TPS) is a system that captures, enters, stores, retrieves, and processes the relevant details of business events and generates the information and documents necessary for running the business.

TPS are aimed at improving the routine business activities on which all organizations depend.

A transaction is any event or activity that affects the organization which occur as part of doing business, such as sales, purchases, deposit, withdrawals, refunds and payments. A transaction is the action that an entity performs beyond itself, i.e., on another entity.

Hence a transaction, at the simplest level, can be defined as an event involving the action of one entity on another.

Common transactions include placing orders, billing customers, hiring employees, and depositing cheques.

The 4 characteristics of TPS include:
*Rapid Response = Fast performance with a rapid response time is critical.
*Reliability = Failure rate must be very low
*Inflexibility = a TPS wants every transaction to be processed in the same way regardless of user. If TPS were flexible there would be too many opportunities for non-standard operations (less consistency).
*Controlled processing = the processing in a TPS must support an organisation’s operations.
