This is a DataCamp course: Often in data science, you'll encounter fascinating data that is spread across multiple tables. This course will teach you the skills you'll need to join multiple tables together to analyze them in combination. You'll practice your skills using a fun dataset about LEGOs from the Rebrickable website. The dataset contains information about the sets, parts, themes, and colors of LEGOs, but is spread across many tables. You'll work with the data throughout the course as you learn a total of six different joins! You'll learn four mutating joins: inner join, left join, right join, and full join, and two filtering joins: semi join and anti join. In the final chapter, you'll apply your new skills to Stack Overflow data, containing each of the almost 300,000 Stack Oveflow questions that are tagged with R, including information about their answers, the date they were asked, and their score.

    The case study in chapter four was highly effective in summarising the entire course coherently. The dataset used in this case study was simple and helpful in intuitively understanding the exercises (or what I was doing). The example used earlier in the course was however a bit more complicated and hampered me in understanding the lesson. It might have been helpful to use simpler tables and an ER diagram to see the relationships between the tables/datasets.
