SQL Data Science Code Challenges

  1. SQL Data Science Code Challenges
  2. Spring 2023
  3. Linkedin Learning
  4. Online learning is done through LinkedIn
  5. I learned cross-joins, filtering, and subsetting data using CASE, WHEN, DATE_PART, COALESCE. The challenges start at a relatively low level of difficulty—column selection, filtering rows from data, sorting and grouping query results—and get progressively tougher, testing me on topics like handling missing and invalid data, calculating moving window averages, and data transformations.
  6. This activity uses SQL and relates to my internship in data science, which is a career path I am pursuing.
