  • Requirements / Prerequisites

    • Prior SQL Fundamentals: Strong grasp of `SELECT`, `FROM`, `WHERE`, `GROUP BY`, `HAVING`, `ORDER BY`, and various `JOIN` types.
    • Data Manipulation Language (DML): Competence with `INSERT`, `UPDATE`, `DELETE` statements.
    • Data Definition Language (DDL): Basic understanding of `CREATE`, `ALTER`, `DROP` for tables, views, and indexes.
    • DBMS Concepts: Familiarity with relational models, primary/foreign keys, data types, constraints, and database architecture.
    • Database Design: Knowledge of normalization forms (1NF, 2NF, 3NF, BCNF) and principles of efficient schema design.
    • Analytical Thinking: Ability to interpret complex database scenarios and apply logical reasoning.
    • Self-Motivation: Willingness to critically evaluate answers and engage in targeted follow-up study.

  • Skills Covered / Topics Tested

    • Advanced Querying: Complex `JOIN` operations, subqueries (correlated/non-correlated), Common Table Expressions (CTEs), and set operations (`UNION`, `INTERSECT`, `EXCEPT`).
    • Transaction & Data Control: `COMMIT`, `ROLLBACK`, `SAVEPOINT` for transactional integrity; `GRANT`, `REVOKE` for database security.
    • Database Object Management: Creation/modification of tables, views, indexes, sequences; understanding various constraints.
    • Programmatic Objects: Designing and implementing stored procedures, functions, and triggers.
    • Database Design & Normalization: Applying normalization levels (up to BCNF) for optimal schema and reduced redundancy.
    • Performance Optimization: Indexing strategies (clustered/non-clustered) and interpreting query execution plans for efficiency.
    • Concurrency & Recovery: Concepts of locking mechanisms, deadlocks, and strategies for backup and recovery.
    • Advanced Analytical Functions: Application of complex aggregate and window functions for sophisticated data analysis.
