What you'll learn
This course provides a comprehensive introduction to SQL (Structured Query Language), the standard language for managing and analyzing data in relational databases. Designed for beginners and intermediate learners, it builds a strong foundation in database concepts while progressively advancing toward practical, real-world applications.
Across five modules, students will:
- Learn the fundamentals of databases and SQL syntax, including how to retrieve and filter data efficiently.
- Master data manipulation techniques to insert, update, and delete records with confidence.
- Apply powerful functions and aggregations to summarize and transform data for analysis.
- Understand relationships and joins to combine data across multiple tables and design normalized databases.
- Explore advanced SQL features such as views, indexes, transactions, and security practices, preparing them for professional use in analytics, reporting, and application development.
By the end of the course, learners will be able to design databases, write optimized queries, and solve business problems using SQL. The program emphasizes hands-on practice, ensuring that participants not only understand the theory but also gain practical skills applicable in data analysis, software development, and business intelligence.
