Master SQL Reporting

Build clear and valuable SQL reports and dashboards, and hone your skills in data cleaning and validation.

In this course, you will apply all the SQL concepts and functions you have learned in previous courses to build your very own dashboard. You will work on an Olympics database to learn about data exploration, data manipulation, data cleaning and validation, and performing complex calculations.

The first chapter aims to get you familiar with the dataset you’ll use, covering some of the essentials you'll need to explore the data properly. Here you will learn how to use ER diagrams and data exploration techniques to get a solid understanding of the data.

Practice Building SQL Reports Using Real Datasets

Next, you’ll learn to build more complex SQL queries to help you explore the data in more detail. The step-by-step approach helps you understand why complex queries require more thought and how they can help you build reports.

Once you get a hang of reporting in SQL, you will learn how to clean and validate SQL data, ensuring our reports are accurate and interpretable.

Develop Your SQL Database Skills

Learn to perform complex calculations using window functions and layered calculations in the final chapter. You will gain hands-on experience building two advanced calculations in particular: the percent of a total calculation and the performance index calculation.

This SQL course is perfect for anyone who will be commonly pulling data from databases and is a great complement for those who use R or Python for data science. This course is part of the SQL for Business Analysts Track and is essential for those who are planning to complete a Data Science or Data Analysis certification with DataCamp.
