Зачем PM знать SQL и как использовать?

PM (Product Manager) needs to know SQL to independently extract and analyze data from the database without relying on developers or analysts. This helps in making informed decisions based on real data.

Using SQL allows:

• To test hypotheses about user behavior
• To analyze product metrics
• To track the effectiveness of new features

An example of a simple query to count new users in the last month:

SELECT COUNT(*) AS new_users
FROM users
WHERE registration_date >= DATE_SUB(CURDATE(), INTERVAL 1 MONTH);

Thus, basic SQL skills help PM quickly obtain the necessary information and improve the product.
