* Transactional Integrity:Provides rollback and commit capabilities in case of errors or failures.
* Common Use Cases:Banking systems, online booking platforms, and financial applications.
Incorrect Options:
* A. Message-oriented middleware:Primarily used for asynchronous message processing, not transaction management.
* C. Remote procedure call (RPC):Facilitates communication between systems but does not manage transactions.
* D. Object request broker:Manages object communication but lacks transaction processing capabilities.
