Detailed Explanation:

GROUP BY Clause:

GROUP BY CustomerID aggregates rows by unique CustomerID values, ensuring calculations are performed per customer.

AVG() Function:

AVG(OrderAmount) computes the average order value for each customer group.

ORDER BY Clause:

ORDER BY AverageOrderAmount DESC sorts the results by average order amount in descending order (highest first). This demonstrates SQL Server’s sorting capability, though it’s optional unless ranking is required.

Optimization Considerations:

Indexing: Creating indexes on CustomerID and OrderAmount would significantly speed up this query in large datasets.
No Unnecessary Features: CTEs, TOP, or OFFSET-FETCH aren’t used here because the query doesn’t require sub-queries, pagination, or row limits.

Result (Based on Sample Data):

| CustomerID |

AverageOrderAmount

| |

|--------------------|

| C002 |

500

| |

C001

| 250 |
