How do RDBMS handle multiple users accessing the same database at the same time?

Multiple users can view the same record concurrently in a Relational Database Management System (RDBMS) because these systems are designed to handle concurrent access efficiently. RDBMS utilizes a concept known as concurrency control, which allows multiple users to read from and write to the database at the same time without interfering with each other’s transactions.

When it comes to viewing records, RDBMS employ various mechanisms that ensure that multiple users can access the same data simultaneously. This functionality is essential for applications where many users need real-time access to information, such as in websites or applications that accommodate several users performing queries or viewing data.

In contrast, options that suggest only one user can view records at a time or that users must queue to access the database do not accurately reflect the multi-user capabilities of RDBMS. Additionally, stating that all users can update records simultaneously oversimplifies the complexities involved in maintaining data integrity and requires some form of locking or transaction management to ensure that updates do not cause conflicts or data inconsistencies.
