• Data manipulation: Inserting, updating, or deleting data in a relational database.

• Data aggregation: Aggregate data using GROUP BY and aggregate functions like SUM and AVG.

• Database management: Create and manage database schemas and indexes to optimize performance.

• Transactional control: Manage database transactions with ACID (Atomicity, Consistency, Isolation, Durability) properties.

• Security and permissions: Control access to data with a granular permissions system.

Its syntax and paradigms form the backbone of most relational database systems. SQL skill sets are vital for data professionals to extract, transform, and load (ETL) data effectively and are used by data analysts, data scientists, and data engineers.

(Know the differences: SQL vs NoSQL.)

Microsoft Power BI
