Final answer:
A temporary file of transaction records, also known as a transaction file or a transaction log, is used to change or update data in a master file.
Step-by-step explanation:
A temporary file of transaction records is used to change or update data in a master file. This temporary file is often referred to as a transaction file or a transaction log. It contains a record of all the changes or updates made to the data in the master file.
For example, let's say you have a master file that stores information about customer orders in a database. When a new order is placed, the details of that order are recorded in the transaction file. Once the transaction is complete, the changes in the transaction file are applied to the master file, updating the customer order information.
This temporary file is essential in ensuring the accuracy and integrity of the data in the master file, as it allows for the recording and tracking of all changes made.
