What This Databases & Backend Course Covers
The course explores advanced SQL querying techniques including INNER, LEFT, RIGHT, and FULL OUTER joins for combining data across multiple tables. Students master subqueries, correlated subqueries, and Common Table Expressions (CTEs) for complex data retrieval. The curriculum covers aggregate functions like COUNT, SUM, AVG, and GROUP BY operations with HAVING clauses. Window functions, ranking operations, and advanced filtering with DISTINCT are thoroughly examined alongside query optimisation strategies.
Educative’s interactive coding environment allows students to execute SQL commands directly in their browser without database installation. Each concept is reinforced through hands-on exercises using realistic datasets and business scenarios. Progressive challenges build complexity gradually, from simple joins to multi-table subqueries. Students practice query troubleshooting, performance analysis, and writing maintainable SQL code through guided projects and immediate feedback systems.
These intermediate SQL skills directly apply to data analyst, backend developer, and database administrator roles across industries. Modern businesses increasingly rely on complex data relationships requiring sophisticated querying capabilities for reporting and application development. The curriculum draws on principles of sql, applied to real-world scenarios.
