SQL helps analysts work directly with structured business data stored in databases.
Many companies store sales, customer, product and operational data in relational databases. SQL allows analysts to retrieve exactly the records needed for analysis.
Important topics include SELECT, WHERE, GROUP BY, ORDER BY, joins, subqueries, CTEs, window functions and aggregate functions.
Analysts often use SQL to prepare data before loading it into Power BI or Python. This makes reporting and analysis workflows more efficient.
Instead of learning only syntax, practice questions such as top customers, monthly sales, product performance, duplicate records and trend analysis.
