    It's a good course with great delivery, correct selection of topics (all basic database operations) and practical examples. The only things I could suggest to improve are: - the last challenge could have been designed better: it's over complex for the objective it is trying to achieve, - sakila database can be downloaded to run locally, which would remove all the references to impact from or on other users, which would make the delivery more fluid.

    Intermediate SQL is a vital skill for effective data reporting and analysis. It allows users to work with data from multiple tables using different types of joins, such as INNER, LEFT, RIGHT, and FULL OUTER joins, to combine and extract meaningful insights. Aggregation functions like COUNT, SUM, AVG, MIN, and MAX help summarize data efficiently, while GROUP BY enables grouping and filtering with the HAVING clause to refine results. Subqueries provide a way to nest queries, enabling dynamic filtering and advanced data manipulation. Window functions, including ROW_NUMBER(), RANK(), and OVER(), allow for advanced analytics like ranking and cumulative calculations. Common Table Expressions (CTEs) simplify complex queries and improve readability by structuring logic with WITH clauses. Additional formatting features, such as the use of CASE, string functions, and date-time operations, enhance the clarity of reports. Lastly, performance optimization techniques, like indexing and efficient que
