In this module, you will explore Structured Query Language (SQL) and gradually master its core concepts related to relational databases. Through hands-on projects, you will navigate the essentials of SQL without overemphasizing programming intricacies.
You’ll build a solid foundation for crafting SQL queries by starting with fundamental keywords like SELECT, FROM, and WHERE. As you progress, you will encounter additional keywords that complement these basics, such as DISTINCT, ORDER BY, GROUP BY, and aggregate functions, which are essential for gaining advanced SQL skills. You will also gain insights into creating tables and managing the information stored within these SQL database tables.
By the end of this module, you’ll have developed querying skills, including the effective use of SQL joins, subqueries for data retrieval, and merging techniques to generate comprehensive reports, all while enhancing your ability to learn SQL effectively.
