By the end of this course, you’ll be able to use SQL to query multiple tables, join data together from different sources, and even extract key business insights from retail databases.
The SQL for Data Analysis course on Udacity teaches you the basics of SQL, including commands like SELECT, FROM, WHERE, and logical operators. You will also learn how to combine data tables using SQL joins to answer more complex business questions. The course covers aggregating data using functions like COUNT, SUM, MIN, and MAX, as well as working with NULL values and writing CASE and DATE functions. Optional advanced lessons cover subqueries, window functions, data cleaning, query optimization, and advanced JOINs.
