SQLD Yellow title

For you who studied hard but still can't solve the problems

This is a lecture on solving Noraengi practical problems.

SQLD - Yellow Book Practice Problem Solutions

For SQL, solving practical problems 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 tackle, known as the Yellow Book Past Problem Solutions Course. The Yellow Book problems are from a book published by the 'Korea Data Industry Promotion Institute', which is the exam organizing body. These are the problems closest to the actual exam questions.


✅Why you should choose this course:

  • Yellow Book 176 Problems Complete Solutions: 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 just the basics? 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 as a data & big data-based professional.

    Materials are provided for a comprehensive exam review, along with practice Oracle and MS SQL scripts, and mock exam solutions. The curriculum is designed for convenient viewing and studying, but it may be a bit difficult to understand for those new to the subject. A more detailed and slower explanation of the problem-solving process and the reasoning behind the solutions would make this an even better lecture.
