A very helpful and valuable course with introductory lectures and practices to get into SQL. The lectures are very digestible, with small and useful quizzes throughout to consolidate the learning. The class is structured well: from basic concepts (what is SQL, what it is used for, what's the benefit of them) to writing slightly more complex queries, as long as you follow through, you'll have a good foundation for using SQL going forward. However, I do think the class may benefit from just one more 'glossary' lesson at the very beginning of the series before diving into the real content to connect the computer science/data science terminology with laymen terms. For example, as someone who works in the basic sciences that has a different definition for 'data modeling', learning what data modeling means in SQL was a surprising but useful fact. Additionally, the datasets could benefit from some context. For example, for the final project (or any project that may involve data manipulation from datasets provided), it would be great to include some data codebook so we know exactly what the data file and the column headers mean before creating new tables/importing data. This could simply be a tutorial video or a website link to the dataset that was provided. Overall very cool class to prepare me for further SQL adventures!
