Kurs SQL Fundamentals for Data Analysis okazał się naprawdę solidnym wprowadzeniem do pracy z bazami danych. Prowadzący krok po kroku pokazuje jak budować zapytania, zaczynając od prostych SELECT-ów, a kończąc na łączeniu tabel i agregacjach, które faktycznie przydają się przy analizie sprzedaży. Podobał mi się sposób tłumaczenia - bez zbędnego żargonu, na konkretnych przykładach biznesowych. Trochę zabrakło mi więcej ćwiczeń z prawdziwymi, większymi zbiorami danych, bo te przykładowe tabele są dość małe. Mimo to po ukończeniu czuję się znacznie pewniej pisząc zapytania do własnych raportów.

About this course
Want to answer your own business questions with data, without waiting for technical help? Learning SQL is the key to unlocking the information stored in company databases and making informed, data-driven decisions.
This course provides a practical, text-based introduction to SQL. You will go from knowing nothing about databases to confidently writing queries to retrieve, filter, sort, and aggregate data, enabling you to perform meaningful analysis and generate reports on your own.
What you'll learn:
* Understand core database concepts and fundamental SQL syntax.
* Learn to retrieve data from tables using SELECT, WHERE, and ORDER BY.
* Practice joining multiple tables to combine related information from different sources.
* Apply aggregate functions like COUNT, SUM, and AVG to summarize data.
* Use GROUP BY to perform analysis on specific segments and categories.
* Write subqueries to answer more complex, multi-step questions.
* Structure complex queries logically using Common Table Expressions (CTEs).
The course begins with essential terminology and database fundamentals before progressively moving into writing practical queries, from simple data retrieval to more complex analytical tasks. You will practice your skills through hands-on exercises.
This course is designed for absolute beginners, including business analysts, marketers, product managers, and anyone who wants to become more data-literate. No prior programming or database experience is necessary.
Start your journey to becoming data-proficient.

O curso de SQL Fundamentals foi exatamente o que eu precisava para começar a trabalhar com análise de dados no meu setor. As aulas sobre JOIN e subqueries foram bem explicadas, com exemplos práticos que fazem sentido no dia a dia de uma empresa. Gostei muito do ritmo, nem muito rápido nem arrastado, dá pra acompanhar mesmo sem experiência prévia em bancos de dados. O único ponto é que alguns exercícios finais poderiam ter mais variação, senti que repetia bastante o mesmo tipo de consulta. Ainda assim, saí do curso conseguindo escrever queries complexas sozinho, o que era meu objetivo.
คอร์สนี้สอน SQL ได้เข้าใจง่ายมาก เริ่มจากพื้นฐานไปจนถึงการเขียนคำสั่งซับซ้อนสำหรับวิเคราะห์ข้อมูลจริง ตัวอย่างที่ใช้สอนก็ใกล้เคียงกับงานที่เจอในบริษัทมาก ทำให้เอาไปใช้ต่อได้ทันที เรียนจบแล้วรู้สึกมั่นใจในการดึงข้อมูลจากฐานข้อมูลมากขึ้นเยอะเลย
Nunca tinha programado e achava que SQL seria impossível, mas comecei a escrever consultas reais já nas primeiras aulas. A forma como explicam SELECT, WHERE e depois os JOINs vai do simples ao complexo sem assustar. Consegui extrair relatórios do banco da empresa que antes dependiam de outra pessoa. A parte de agrupar dados com GROUP BY foi a que mais usei no trabalho. Só faltou um pouco mais sobre otimização de consultas, mas no geral valeu muito a pena.
Без опыта в коде научилась писать запросы с JOIN и фильтрами, хотелось бы только больше практики с подзапросами.
