Learn to use Structured Query Language (SQL) to extract and analyze data stored in databases.
In the course SQL for Data Analysis on Udacity, you will learn the basics of SQL, including how to write common commands such as SELECT, FROM, and WHERE, as well as how to use logical operators. You will also learn about SQL joins, including INNER JOINs and LEFT JOINs, to combine data from multiple tables. The course covers SQL aggregations, teaching you how to write common aggregations like COUNT, SUM, MIN, and MAX, as well as how to work with NULL values and use CASE and DATE functions. Additionally, you will learn about subqueries and temp tables, which allow you to run multiple queries together and access a table with more than one query. The course also covers SQL data cleaning techniques and introduces window functions, which can be used to tackle more complex analysis tasks.
