longvacation
No fluff, just the "core" of ChatGPT's 100% utilization. Utilize it well, and your MD, marketing tasks will be 10x faster.
Beginner
ChatGPT, Python, Web Crawling
This course is suitable for MDs and marketers who want to analyze large amounts of e-commerce data using SQL, as well as job seekers (new or junior) in development roles who want to understand the flow of e-commerce data.

SQL
Data Analysis
Querying and analyzing vast amounts of data in the database
From SQL utilization, data extraction, and analysis to visualization...
We will build your confidence in practical application!
Because you only learned grammar
and haven't worked with
real data!
Because you don't fully
understand the DB structure
actually used in practice!
Because you don't know how to
actually
utilize the output data!
👉 The reason SQL is difficult to use is, after all, because you haven't encountered a SQL course tailored to practical work yet.
Do you want to use SQL "well"? There are many SQL courses out there, but it's not easy to actually apply SQL properly. This is because it's difficult to find a course that teaches using real-world business data.
This course is different from existing courses that only teach SQL syntax.
Instead, you will learn how to “solve problems through SQL.”
You will learn how to freely use SQL based on
actual e-commerce service data
ranging from products to discounts, orders, payments, and refunds.
You will understand the complex data flow of products, discounts, orders, payments, and refunds, and gain access to data that is likely to be used in practice. In addition, you will learn simple data visualization methods to create intuitive business reports and analysis materials yourself, enabling a higher level of data analysis.
Real SQL learning for practitioners! Of course, it will be even more helpful if you are in an e-commerce-related industry. We will help you develop the ability to identify “which data to extract with which query in what situation.” Let's take on the challenge together!
Those who want to learn SQL or
are working in the
e-commerce industry
Those who want to analyze
actual service data
(MDs, Marketers, Planners)
Junior developers
who want to study
e-commerce DB structures
Those who want to try
SQL data visualization
using Python
Real-world examples that build practical skills
We will build a database and conduct hands-on practice by crawling actual product information from Coupang product pages.
So that you can utilize data "well"
You can learn useful analysis methods through SQL and Python visualization.
Get closer to SQL queries
The lectures focus on data commonly used in e-commerce practice, and we provide intensive instruction on how to write SQL queries required for various situations you may encounter at work.
Complex DB structures are also OK
You will be able to easily understand and analyze the database structures for e-commerce orders, payments, refunds, and discounts. This will help you in practical service operations where data flows are complex.
“I have infused the know-how of an e-commerce developer into this lecture.”
Q. Can I take this course even if I have no prior knowledge of SQL?
The curriculum is divided into sections, and in the first section, I will teach you how to write SQL code from a beginner's perspective. Rather than just explaining basic SQL, the course is designed to gradually introduce advanced SQL techniques as the sections progress, allowing you to learn and apply them naturally.
Q. I am working as an MD/Marketer in e-commerce. Specifically, what can I learn through this course?
You will be able to write SQL yourself without having to wait indefinitely for the development team or being told that data extraction and other requests are currently impossible.
Q. I am preparing for a job as a new developer. What can I learn from this?
You can learn specifically about database configurations that are difficult to learn in school or academy classes. It is especially helpful if you want to get a job at a service company with complex data structures and flows, such as e-commerce. This will directly lead to an increased understanding of the role and will be a useful lecture for interviews or career decisions.
Q. Is there any prior knowledge or preparation required for the class?
No prior knowledge is required. However, a personal PC is necessary as the lecture content and hands-on exercises require the installation of software (free).
Q. Since actual in-house e-commerce data would pose security issues, how do you plan to explain this?
The class will be conducted based on data constructed by crawling product information, selling prices, and discount details from product data displayed on the e-commerce platform Coupang.
