تفاصيل العمل

SQL database analysis involves querying to:

1. **Retrieve Data:** Use SELECT to fetch specific columns from tables.

2. **Filter and Sort:** WHERE for data filtering, ORDER BY for sorting.

3. **Aggregate:** Employ functions like SUM, AVG, COUNT, and GROUP BY for summarized data.

4. **Joins:** Combine data from different tables using JOIN operations.

5. **Modification and Integrity:** UPDATE, INSERT, DELETE for data modification; Constraints (UNIQUE, NOT NULL, FOREIGN KEY) for maintaining integrity.
