Answer:
The ability to perform multiple queries and analyses on a database simultaneously is an advantage of database concurrency. Concurrency refers to the ability of multiple users or processes to access and modify the data in a database at the same time without causing conflicts or errors.
In the record store example you provided, two users are able to perform different queries and analyses on the same database at the same time without affecting each other's work. This demonstrates the ability of the database to handle concurrent access and allow multiple users to work with the data simultaneously.
Other advantages of database concurrency include improved efficiency and productivity, as multiple users can access and work with the data at the same time, and better data integrity, as the database is able to prevent conflicts and errors that may occur when multiple users access and modify the data simultaneously.
