SQL for Data Analysis | Udacity

SQL for Data Analysis | Udacity is a beginner-level course designed for learners who want to work with data quickly. The course runs for one month and is self-paced, so you can study on your own schedule. All content is in English.

This course teaches you how to write SQL queries to explore, clean, and analyse data. You start with basic SQL commands and move on to more advanced topics like joins, aggregations, and subqueries. Later modules cover data cleaning and window functions, which help you calculate running totals and compare rows without grouping. Each topic is built around real data tasks, not just syntax drills.

• Write SELECT statements to pull data from tables
• Use JOINs to combine data from multiple tables
• Group data with aggregations such as COUNT, SUM, and AVG
• Filter groups with HAVING and use subqueries
• Clean messy data and prepare it for analysis
• Apply window functions for running totals and row-level comparisons

The course is free to audit. It is a good fit for beginners who have no prior experience with SQL or databases. Learners who want more hands-on practice with a specific database system may prefer the Oracle SQL courses listed on CoursesGlobal, which include a complete introduction and a certification path. Those looking for a broader data-skill set might also explore the SQL Development with MS SQL Server course on Udemy, which runs to a master‑level scope.

This course does not cover database administration, data modelling, or advanced performance tuning beyond the window‑function modules. If your goal is to manage servers or design schemas, the MS SQL Server course or the MIS Training course that blends Excel, Access, and SQL would be a better starting point.
