volume_mute

Which of the following best describes a Transaction Processing (TP) system?

A database-centred application that processes user requests for information and updates a database, where a transaction is a sequence of operations treated as a single atomic unit

A system that compiles source code into executable machine code

A system that processes batches of data files without any user interaction

A system that monitors network traffic and filters packets in real-time

Correct Answer

A database-centred application that processes user requests for information and updates a database, where a transaction is a sequence of operations treated as a single atomic unit

Explanation

Transaction processing (TP) systems are database-centred applications that process user requests for information and update the information in a database. A database transaction is a sequence of operations treated as a single (atomic) unit - all operations in the transaction must be completed before database changes are made permanent, ensuring failure does not create inconsistencies.
