What term refers to a database management system's method of allowing multiple user access without data conflict?

The correct term that describes a database management system's method of allowing multiple user access without data conflict is concurrency control. This concept is crucial in multi-user environments where several transactions can occur simultaneously. Concurrency control ensures that database transactions are executed in a way that preserves the integrity and consistency of the data, preventing issues such as lost updates, dirty reads, and other anomalies that might arise from concurrent data access.

Concurrency control mechanisms can include locking strategies, timestamp ordering, and multi-version concurrency control, all designed to manage how data is accessed and manipulated by multiple users at the same time. By implementing these strategies, a database can maintain accuracy and reliability, enabling users to work concurrently without interfering with each other's transactions.

The other options represent important concepts within database management, but they do not specifically address the challenge of enabling multiple users to access data simultaneously without conflicts. Data integrity focuses on the accuracy and consistency of the data itself. Normalization is the process of organizing data to minimize redundancy, while transaction management encompasses the techniques used to ensure all parts of a transaction are processed correctly. While these aspects contribute to the overall functionality of a database, they do not directly tackle the issue of managing concurrent access.
