Normalization (1NF to BCNF): Next
Module: Schema Design & Advanced DDL
Denormalization Strategies: When and how to selectively denormalize for performance
Constraints & Integrity: Enforce referential integrity in normalized schema
Indexing Strategies: Index foreign keys for fast joins in normalized tables
Materialized Views: Pre-compute expensive joins for read-heavy workloads
Database Design Patterns: Common patterns for normalized schemas
Query Optimization: Optimize joins in normalized schema
Partitioning: Partition large normalized tables for performance
Normalize unnormalized table to 1NF (eliminate repeating groups)
Identify partial dependencies and convert to 2NF
Identify transitive dependencies and convert to 3NF
Check BCNF violations and fix (every determinant is candidate key)
Design normalized schema for e-commerce system (products, orders, customers)
Design normalized schema for social media (users, posts, comments, likes)
Identify functional dependencies in given schema
Compare normalized vs unnormalized performance (measure query times)
Explain 1NF, 2NF, 3NF, BCNF with examples
What are functional dependencies? How to identify them?
What is the difference between partial and transitive dependencies?
When should you denormalize? What are the trade-offs?
Design normalized schema for library system (books, authors, members, loans)
Identify normalization violations in given schema and fix
How does normalization affect query performance?
What is BCNF? How is it different from 3NF?
