A student's monthly fee changes, we must record the change in multiple receipts for student enrolled in many courses, which type of anomaly exists in this situation?
Correct answer: B. Update anomaly
- A. Modification anomaly
- B. Update anomaly
- C. Insertion anomaly
- D. Deletion anomaly
Explanation
In this scenario, the student's monthly fee represents a single piece of information that applies to all their course enrollments. If the fee changes, you need to update it in every receipt where it's recorded. This is a classic example of an update anomaly. Update anomalies can lead to inconsistencies in the data if the fee is not updated in all the receipts. For instance, some receipts might reflect the old fee while others reflect the new fee

The subject includes primary and foreign keys, normalization, SQL commands such as SELECT, INSERT, UPDATE and DELETE, queries, forms and reports, while distinguishing a database from a spreadsheet used for simple tabular data.
