This is a lecture on solving Noraengi practical problems.

SQLD - Yellow Book Practice Problem Solutions

For SQL, practical problem solving is especially important.

I studied both SQL theory and practice diligently, but when I actually look at SQLD exam questions, my mind goes blank.

This is the experience of almost 99% of test takers.

It's difficult to easily solve problems with lots of black SQL queries on a white background.

Moreover, it's problematic that they don't even release past exam questions.

So, I developed a practical problem-solving course that everyone should try, known as the Yellow Book Practice Problem Solution Course. The Yellow Book problems are from a book published by the 'Korea Data Industry Promotion Institute', which is the exam organization. These are the problems closest to the actual exam questions.


Why you should choose this course:

  • Complete Solutions for Yellow Book 176 Problems: Provided with corrections to errors found in existing Yellow Book solutions

  • Practice Scripts Provided: Oracle and MSSQL Server practice scripts and data provided

  • 3 Practice Tests Provided: End with Noraengi? No! 3 practice tests provided that you can solve on your own

Important Notice: Please be sure to read the following information before enrolling in the course.🙂

  • Recommended for intermediate level and above, those who have completed theoretical studies.

  • Beginners, please study the theory first before taking the course. The content may be more difficult than you think.

  • Problem-solving lectures focus on solving problems. You need to study and research on your own for areas where you lack theoretical understanding.

The SQLD certification is the first step for you to grow into a data & big data-based professional.

    시험 총 정리를 위한 자료가 제공되고 실습 가능한 오라클, msSql 실습 스크립트, 모의고사 풀이가 제공됩니다. 보고 공부하기 매우 편리하게 커리큘럼이 짜여져 있으나, 처음 접하는 분들이라면 조금 이해가 어려우실 수 있습니다. 문제를 풀어나가는 과정이나 왜 이렇게 나오는지에 대해 조금 더 자세하고 천천히 알려주시면 더욱 좋은 강의가 될 것 같습니다.

      안녕하세요. 좋은 의견 남겨주셔서 감사드립니다. 문제의 난이도가 있다보니, 이해가 좀 어려웠을 수 있을거 같네요. 말씀하신 점을 보완하기 위해서 수업노트에 설명을 조금 더 상세하게 보완해두었습니다. 감사드리구요. 혹시 어려운 점이 있으면 질문을 활용해주시길 부탁드릴게요. :) 즐거운 토요일 보내세요. 감사합니다.
