Learn common components of global-scale services through popular papers, books, and articles.

This course provides a step-by-step learning path, ranging from the fundamental usage of MySQL to advanced techniques required in real-world production environments. It covers a wide range of topics, including data modeling techniques based on various case studies and practical data, evaluating the effectiveness of Foreign Key designs, analyzing Google Calendar schema DDL, and modern DDL design principles. Through this course, you will gain an in-depth understanding of how to utilize MySQL as a core system component rather than just a simple database.

We will completely resolve the anxiety of those who felt frustrated by blindly copying AI-generated code without understanding the internal workings of HTTP or the causes of unexpected hanging.

Developing an 'Autonomous' Premium Reservation Agent Backend Using Spring AI + JPA + MySQL Beyond Chatbots to Agents: The Standard of Tool Calling and Prompt Engineering

A smooth-flowing guide to Express.js, from basics to real-world application! A backend journey to truly master everything from basic server concepts to completing a CRUD project through hands-on implementation.

This course goes beyond basic CRUD-level database operations, equipping you with practical PostgreSQL skills essential for the AI era from a real-world perspective. Drawing on AI development experience in Silicon Valley, you will learn step-by-step how to design and leverage JSON, indexing, transactions, and pgvector in actual production services, and master the techniques to resolve complex data structure and performance issues.

This course focuses more on data modeling through entity design than on JPA technical explanations. Based on the principle that solid DB design is the foundation of application development, we analyze various design patterns—such as one-to-many, many-to-many, inheritance, and collections—alongside business scenarios. You will learn by directly observing the process of code being transformed into actual tables on screen. To ensure immediate practical application, we provide business use cases, source code, and test codes for each design pattern.

We enable you to fundamentally understand and resolve issues where Hangeul appears broken on web pages or in databases, or files contain unknown characters.
