The selection includes Oracle's "Databases for Developers: Foundations" for industry-recognized certification, freeCodeCamp's "Relational Databases" for project-based learning, and Kaggle's "Intro to SQL" for practical, bite-sized lessons. Other options cover structured career learning with Analytics Vidhya's "Essential SQL Skills for Data Beginners," professional development via LinkedIn Learning's "SQL Essential Training," database design with OpenClassrooms' "Implement a Relational Database with SQL," and an unconventional approach using Taylor Swift's discography in CodeSignal's "Journey into SQL."
