课程概述

By completing this course, learners will design relational databases, construct tables with constraints, implement joins, and analyze business data using advanced SQL queries. They will also apply aggregate functions, manage NULL values, pivot datasets, and create subqueries to extract actionable insights. This case study–driven course is designed for learners who want hands-on experience in SQL with Oracle SQL Developer. Beginning with database and table creation, participants progress through increasingly complex scenarios such as finding the nth highest salary, department-level analysis, hierarchical queries, and advanced filtering with GROUP BY and HAVING. Learners will gain practical problem-solving skills by working through real-world style challenges instead of abstract examples. What makes this course unique is its structured approach: each module builds on the last, moving from foundational database creation to advanced business applications. Instead of focusing solely on syntax, the course emphasizes how to think in SQL — transforming raw data into meaningful business insights. By the end, learners will have the confidence to tackle real database challenges, making them more effective in roles across data analysis, business intelligence, and application development....
