is a style of computing that divides work into individual, indivisible operations, called transactions

A transaction processing system or transaction server is a software system, or software/hardware combination, that supports transaction processing.

Transaction processing systems provide three functional

System runtime functions System administration functions Application development functions

Transaction processing systems provide an execution environment that ensures the integrity, availability, and security of data. It also ensures fast response time and high transaction throughput.

Transaction processing systems provide administrative support that lets users configure, monitor, and manage their transaction systems.

Transaction processing systems provide functions for use in custom business applications, including functions to access data, to perform intercomputer communications, and to design and manage the user interface.

The earlier transaction processing systems were manual systems.

Clerks use manual system in recording, data keeping, managing and forwarding.

Customers and suppliers files separately managed by manually system.

Computer system resolve all problems which were faced by manual work.

Computer system covers all transactions efficiently, quickly and beneficial.

Online transaction process

OLTP has also been used to refer to processing in which the system responds immediately to user requests. An automated teller machine(ATM) for a bank is an example of commercial transaction processing application. Online transaction processing applications are high throughput and insert or update-intensive or database management. These applications are used by concurrently by hundred of users. The key goals of OLTP applications are availability speed, concurrency and recoverability.
