This course covers everything you need to start querying data with SQL for data analytics without prior knowledge.

It covers the following topics.

• Introduction to relational databases and why they matter for data analytics
• Installing a server and restoring a demo database, so you immediately apply the things you are learning
• Writing basic SELECT queries and modifying the output columns
• Filtering the result set using WHERE
• Grouping and aggregating data
• Joining data from different tables to generate insights by combining data sources

It uses the widely SQL Server from Microsoft, which you can highly likely encounter in companies. But in the end, the platform is not relevant, as SQL is a universally applicable skill.
