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.
