Sli.do 7 features
SSS
Select Star SQL 5 features
  • Audience Q&A
  • Polls
  • Quizzes
  • Word clouds
  • Surveys
  • Google Slides integration
  • Zoom Integration
  • Completely Free
    Select Star SQL is entirely free to use with no paywalls, subscriptions, or hidden costs. This makes it accessible to anyone who wants to learn SQL regardless of their financial situation.
  • 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.
  • Well-Structured Progressive Curriculum
    The course is organized in a logical progression from basic SELECT statements to more advanced concepts like aggregations, joins, and subqueries, allowing learners to build knowledge incrementally without feeling overwhelmed.
  • No Setup Required
    There is no need to install any software, set up a database, or configure an environment. Learners can start writing SQL queries immediately in their web browser, removing a significant barrier to entry for beginners.

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.
