A transaction processing system is a type of information system.
TPSs collect, store, modify, and retrieve the transactions of an organization.
A transaction is an event that generates or modifies data that is eventually stored in an information system.
In a TPS, there are 5 different types of files.
The TPS uses the files to store and organize its transaction data:
* Master file:
Contains information about an organization's business situation.
Most transactions and databases are stored in the master file.
* Transaction file: It is the collection of transaction records.
It helps to update the master file and also serves as audit trails and transaction history.
* Report file:
Contains data that has been formatted for presentation to a user.
* Work file:
Temporary files in the system used during the processing.
* Program file:
Contains the instructions for the processing of data.
