MySQL Data Types Deep Dive: VARCHAR vs TEXT, DECIMAL for Financial Precision & JSON Column Performance 03. Primary Keys, Foreign Keys, Unique Constraints & Referential Integrity Rules (CASCADE / RESTRICT)

04. SQL Joins Masterclass: INNER, LEFT, RIGHT, FULL OUTER & Cross Joins Execution Strategies 05. Subqueries vs Common Table Expressions (WITH CTE) & Recursive CTEs for Hierarchical Tree Queries 06. SQL Window Functions: ROW_NUMBER(), RANK(), DENSE_RANK(), NTILE(), LEAD() & LAG() for Analytics

07. InnoDB Architecture: The Buffer Pool, Change Buffer, Redo Log (WAL), Undo Log & Doublewrite Buffer 08. Clustered Indexes vs Secondary Indexes: How B+ Tree Data Pages are Organized on Disk 09. The B+ Tree Node Structure: Fanout, Height Calculations & Why B+ Trees Outperform Binary Trees for Disk I/O

10. ACID Properties Deep Dive: Atomicity (Undo Log), Consistency, Isolation & Durability (Redo Log) 11. Transaction Isolation Levels: Read Uncommitted, Read Committed, Repeatable Read (Default) & Serializable 12. Multi-Version Concurrency Control (MVCC): Read Views, Row Versioning & Non-Locking Consistent Reads 13. InnoDB Locking Engine: Record Locks, Gap Locks, Next-Key Locks & Resolving Deadlocks in High Concurrency

14. Query Optimization with EXPLAIN & EXPLAIN ANALYZE: Type column (ALL, index, range, ref, eq_ref, const) 15.
