• Interactive Hands-On Learning
  The platform provides an interactive SQL environment directly in the browser where learners can write and execute real SQL queries against actual datasets, reinforcing concepts through practice rather than passive reading.
• Real-World Dataset
  The course uses a compelling real-world dataset about Texas death row executions, which makes the learning experience more engaging and meaningful compared to abstract or contrived examples.

Possible disadvantages

• Limited Scope
  The course covers only fundamental SQL concepts and does not address more advanced topics like window functions, CTEs, indexing, database design, or performance optimization, which are essential for professional SQL usage.
• Single Database Dialect
  The platform teaches SQL using SQLite, and does not cover syntax differences or features specific to other popular database systems like PostgreSQL, MySQL, SQL Server, or Oracle, which learners may encounter in real jobs.
• No Certificate or Credential
  Completing the course does not provide any formal certificate, badge, or credential that learners could use to demonstrate their SQL skills to potential employers or on professional profiles.
• Limited Practice Exercises
  While the course includes some exercises, the total number of practice problems is relatively small compared to dedicated SQL practice platforms, which may not be sufficient for learners who need extensive repetition to solidify their skills.
• Single Dataset Can Feel Restrictive
  Using only one dataset throughout the entire course means learners do not get experience working with diverse data schemas, table relationships, or different types of data, which limits exposure to varied real-world scenarios.
