Summary: 데이터리안 launches Lunar New Year discount event

Why It Matters: The competitor is using a seasonal holiday to lower the barrier for new students. This could lead to a quick increase in their student numbers and market share during the February period.

What Changed:

• Added a "Lunar New Year Special Discount" promotion for the SQL Bootcamp (Basic) available until February 13th.
• Updated the "Popular Blog Posts" section with new articles about data books and MySQL installation.
• Refreshed the "Recommended Articles" list with new topics like SQL certificates and problem-solving skills.
• Replaced several technical GA4 and UTM blog links with more general data analysis case studies from companies like Toss and Danggeun.
