SQL자격검정 실전문제 풀이는 물론 SQL 학습과 관련한 과정입니다.  

특히, SQLD 자격을 위한 시험 준비를 위해

"SQL 자격검정 실전문제 - 한국 데이터진흥원"를 교재로 채택했습니다.

      🗒 영상 : M1 ~ M9

      🗒 문항 : 총 52 문항

      🗒 시간 : 2시간 48분 38초

 

 

이 외에도 SQL에 대한 학습과 관련하여 기본 지식을  

쌓을 수 있도록 가장 필수적인 내용을 정리한 자료도  함께 마련했습니다. 

SQLD 자격을 취득하기 위한 SQL 학습으로  진행되는 것이 아쉽기도 합니다. 

물론 이러한 점을 고려했고 더 나아가 실무적인 SQL 활용 스킬(skill)의 향상을 위해

다양한 정보를 제공할 수 있도록 계획하고 있습니다.

 

 

SQL을 학습하고자 하는 여러분 모두에게 

유익한 정보를 제공할 수 있도록 노력하겠습니다.

 

 

감사합니다.
