• Part 4 - Oracle architecture, licensing reality, and Tibero migration guide
• Part 5 - Index design, reading execution plans, transactions and lock management
• Part 6 - Backup strategies, connection pooling, and session management

• Web developers who use databases daily but want deeper understanding
• Backend engineers preparing for system design interviews
• Developers migrating between Oracle, MySQL, PostgreSQL, or Tibero
• Anyone who wants to write faster queries and design better schemas

Includes 8 architecture diagrams, 3 appendices (SQL syntax comparison, data type mapping, error message dictionary), and practical examples from real-world projects.
