Learners will be able to design relational database schemas, create normalized tables, and analyze employee data using practical SQL queries in PostgreSQL. By completing this course, learners will develop the ability to join multiple tables, evaluate employee appraisals, and derive salary-based insights through real-world querying scenarios.

This course is designed as a hands-on PostgreSQL project that moves beyond theory and focuses on applied problem-solving. Learners begin by setting up a PostgreSQL environment and building foundational employee and appraisal tables. They then progress to writing JOIN queries, analyzing performance data, and extracting meaningful salary insights, mirroring tasks commonly performed by data analysts and backend developers. What makes this course unique is its project-driven approach centered on a realistic employee records use case. Instead of isolated SQL concepts, learners work through an end-to-end workflow—from database setup to final query output—gaining practical experience that directly translates to workplace scenarios. By the end of the course, learners will have strengthened their SQL proficiency, improved their data analysis skills, and gained confidence in using PostgreSQL to solve structured data queries in real-world projects.
