Great breakdown of relational algebra operations! Your explanation clearly distinguishes between set operations and relational database operations, making it easier to understand their functions. The SQL examples you provided really help in demonstrating how these theoretical concepts are applied in practice. Particularly, the use of UNION, INTERSECT, and EXCEPT is essential for anyone working with databases. It would be interesting to see more examples or scenarios where these operations can be utilized effectively, especially in complex queries. Keep up the good work!
