Test your knowledge of managing outpatient cases using MySQL databases. Dive into SQL queries, schema design, and data manipulation tailored for healthcare settings.
1. Which SQL operation would you use to link patient records with their respective outpatient appointments?
CROSS JOIN
INNER JOIN
SELF JOIN
OUTER JOIN
2. What is the primary reason for using foreign keys in a healthcare database?
To manage backups
To accelerate queries
To enforce referential integrity
To store patient data
3. Which clause correctly filters appointments to show past cases only?
GROUP BY appointment_date
ORDER BY appointment_date ASC
WHERE appointment_date < NOW()
SELECT appointment_date FROM appointments
4. How does normalization affect database configuration in healthcare management?
Minimizes redundancy, affects complexity
Minimizes redundancy, loses integrity
Maximizes redundancy, improves speed
Increases redundancy, simplifies design
5. What SQL function counts outpatient cases per doctor when correctly aggregated?
COUNT(appointment_id)
COUNT(*) WITH GROUP BY doctor_id
MAX(appointment_date)
SUM(amount)
6. When designing a schema, how can integrating ICD-10-CM codes enhance database functionality?
Eliminates the need for other codes
Standardizes diagnosis data
Complicates queries
Increases record size
7. Which relational key is essential to defining a one-to-many relationship from Patient to Appointment?
patient_id as foreign key
appointment_id as primary key
doctor_id as foreign key
billing_id as unique key
8. What assessment is crucial when deciding on using an INNER JOIN versus other JOIN types in SQL?
Only one side needs a match
Ignores relationship types
Includes unmatched from both tables
Matches all overlapping records
9. Which aspect of database design does normalization potentially impact most significantly?
User interfaces
Query speed
Data redundancy
Backup procedures
10. In a healthcare schema, how do foreign keys interact with patient and appointment tables?
