Database

Practical Oracle SQL Utilization

We would like to provide an opportunity to learn SQL, a language used in relational databases, in general. In particular, we wrote the execution examples in the ORACLE environment. The learning content is largely divided into 2 parts and a total of 11 lectures. After learning the entire content, you can cultivate the ability to perform tasks in a database along with the general knowledge of SQL, and you can also prepare for the nationally certified SQL developer qualification.

SQL자격검정 실전문제 풀이는 물론 SQL 학습과 관련한 과정입니다.  

특히, SQLD 자격을 위한 시험 준비를 위해

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

 

 

🔔  1과목

      🗒 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.

          기초적인 내용은 알고 있는 게 있어서 알아 듣겠는데, 조금만 난이도가 올라가도 개념에 대한 설명의 도약이 많아 알아 듣기 어렵습니다. 실습을 따라할 수 있으면 더 좋을 것 같습니다. 초보자에게는 추천하지 않습니다. 알아들을 수 있는 정도의 중급자라면 굳이 듣지 않아도 될 것 같구요.
