Database fundamentals: An application in which only one user accesses the database at any given time is an example of which type of database application?

Introduction / Context:
Classifying database applications helps determine concurrency control, transaction management, and performance needs.

Given Data / Assumptions:

• Exactly one user accesses the database at a time.
• No concurrent access from multiple clients.

Concept / Approach:
A single-user database application is designed for one active user. This minimizes locking contention and simplifies transaction logic.

Step-by-Step Reasoning:

Verification / Alternative check:
Contrast with multiuser systems (OLTP, e-commerce) where multiple concurrent sessions require robust isolation.

Why Other Options Are Wrong:

• Multiuser → implies concurrency.
• E-commerce → typically multiuser with web-based concurrency.
• Data mining → analytical workloads; not a single-user definition.

Common Pitfalls:
Assuming “one user right now” means multiuser isn’t needed; here, the definition is explicitly single-user by design.

Final Answer:
single-user database application
