• Module 1: Advanced Relational Database Design
• Normalization beyond 3NF (BCNF, 4NF, and 5NF)
• Denormalization strategies for read-heavy applications
• Entity-Relationship (ER) modeling and converting ER diagrams into optimized physical relational schemas
• Module 2: Query Optimization & Performance Tuning
• Analyzing query execution plans with EXPLAIN and EXPLAIN ANALYZE
• Optimizing SELECT, JOIN, subqueries, and aggregation queries
• Execution engine architecture and memory management (InnoDB Buffer Pool)
• Module 3: Advanced Indexing Strategies
• B-Tree, Hash, Full-Text, and Spatial (GIS) indexing mechanisms
• Composite index design, index selectivity, and covering indexes
• Identifying and eliminating unused, redundant, or missing indexes
• Module 4: Stored Programs, Triggers, and Functions
• Writing stored procedures and user-defined functions (UDFs) using control flow logic
• Event-driven automation using database triggers (BEFORE/AFTER Insert, Update, Delete)
• Scheduling periodic database tasks with MySQL Event Scheduler
• Module 5: Transactions, Concurrency, and Locking
• Practical implementation of ACID properties
• Transaction isolation levels (Read Uncommitted, Read Committed, Repeatable Read, Serializable)
• Managing deadlocks, row-level locking, and optimistic/pessimistic concurrency control
• Module 6: Backup, Recovery, and Security Administration
• Backup methodologies: Logical (MySQL dump) vs. Physical (Percona XtraBackup/MySQL Enterprise Backup)
• Point-in-Time Recovery (PITR) using binary logs (binlog)
• Role-based access control (RBAC), data encryption at rest and in transit, and security hardening

• Basic SQL knowledge; Understanding of data structures
