Our Verdict
SQL Tuning course on Udemy has been well-received with a 4.28 global rating. The content is primarily tailored for beginners and covers the fundamentals comprehensively, making it an ideal starting point for those new to Oracle SQL tuning. However, the focus on basic concepts may leave experienced students seeking more advanced techniques or real-world scenarios for practice. Moreover, the course centers around Oracle SQL, which might limit its value for users of other database systems. Additionally, a few reviewers expressed disappointment with the limited hands-on exercises and inadequate large dataset examples, which could have enhanced the overall learning experience by offering practical applications and test scenarios.
