Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Supports simultaneous multi-user access
Databases support concurrent multi-user access with locking mechanisms, while flat files cannot handle simultaneous writes safely.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Simpler to set up and manage
Why it's wrong here
While flat file systems can be set up with minimal overhead, they lack the relational integrity and concurrent-access controls that a database management system provides. This option is tempting because for a small, single-user list of records, a flat file is indeed quick to configure. However, in a scenario requiring simultaneous multi-user updates and enforced data consistency across customer records, the absence of transaction management and referential constraints makes a flat file system unsuitable.
- ✓
Supports simultaneous multi-user access
Why this is correct
Databases are designed for concurrent access with transaction controls.
- ✗
Stores data in a non-structured format
Why it's wrong here
Databases store data in structured formats; flat files can be unstructured.
- ✗
No need for a query language
Why it's wrong here
Databases use query languages like SQL, which is a feature, not a disadvantage.
