Large-Scale Systems Design Part 1

Learn and create Git actions yourself, the de facto standard for version control tools!

You can learn about the core functions of MySQL and how to effectively use them in your work. You can also gain a new understanding of important parts that you have been using for a long time and have overlooked, and gain in-depth database knowledge.

Practical Payment System Development Course, learn by code, and cover the knowledge needed to implement a real system.

Have you ever wondered why we use these techniques while watching the Clone Coding lecture? Let me give you a big picture of backend development!

Beyond basics like API design, CRUD implementation, and JWT authentication, all the way to backend architecture design! This is an introductory system design course to help you build 'your own backend architecture' that you can confidently discuss in interviews.

Modern digital products and services start from small ideas and grow to be loved by millions of users. The key to making this possible is scalable system design. In this course, you will learn the design principles and implementation methods for growing from small to large systems.

In the software system design course taught by Silicon Valley engineers, you will learn the design principles and architectural patterns of large-scale systems and how to build stable and scalable software solutions. In addition, you will cover performance optimization and fault response strategies through practical cases.

Learn database design systematically through three stages: conceptual, logical, and physical, and strengthen your capabilities with a practical shopping mall project. Acquire real-world expertise through modern design techniques and the latest trends.

You can master Database development, which is essential for mobile/web development, through MySQL.

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.

Along with reading, writing, and arithmetic, computational thinking is an essential skill that everyone living in the AI era must possess. Simply put, computational thinking can be defined as thinking like a programmer or a computer scientist. This course replicates an actual full-semester university lecture and covers essential content for those new to programming or beginners planning to major in computer science. Furthermore, through this course, non-computer science majors or those with a background in the humanities can develop the ability to communicate easily with professional programmers. Even in an age where learning prompts for "AI vibe coding" is necessary, computational thinking will help you develop the ability to instruct AI more accurately and effectively.

You can solve design problems by writing code in a formatted way. You can understand code or patterns written by other programmers.

This lecture comprehensively organizes the content that would be good for those who want to get a job as a new Spring Java backend developer, especially those who are about to have an interview.

SQL data analysis! We will teach you how to solve practical problems that are applicable in the field, quickly and easily!

This is a course on creating practical Unity games with databases. It covers topics that are usually difficult to encounter, explained through lectures.

Extract and utilize data through Oracle 18c and become a database expert!

Introduction to SQL Data Analysis! Quick and easy to understand with practical problem solving!

Through this course, you can acquire the concepts and practices of Information Strategic Planning.

I will transform the Engineer Information Processing written exam (Subjects 1–5) from a "test you solve by memorizing" into a "test where you connect clarified points directly to your score." This is an ultra-compressed lecture designed to help you grasp the entire flow within 3 days. It extracts only the core concepts repeated in past exams, structured to be understood even if viewed right before the test. The course is designed for short-term success by clearly distinguishing between frequently confusing concepts, trap points in multiple-choice options, and what needs to be memorized versus what only needs to be understood. "I'm short on time, but the scope is too broad." "I feel like I know the material when reading the book, but I keep getting the questions wrong." This lecture is for students facing these exact challenges.

This course teaches MS-SQL through baseball/company databases.

By implementing various practical data analysis cases using SQL, you can simultaneously improve your data analysis and SQL utilization skills.
