Q&A 💬

Q. Why should I learn SQL?

They say data is the oil of the 21st century. It's virtually impossible to find an industry that doesn't utilize data. Therefore, data-handling skills are essential these days, and SQL is considered one of the most common means of accessing data. Furthermore, cloud-based machine learning services are increasingly utilizing SQL. Furthermore, SQL skills are increasingly required for IT recruitment.

Q. Can non-IT majors learn it too?

Of course. Data itself isn't limited to IT majors. Data handling skills are essential for a wide range of talents across all industries, regardless of their major.

Q. What are the main features of the class?

This course aims to teach skills that can be immediately applied in the workplace. Therefore, we use a database similar to those used in the field as our practice database. Furthermore, to enhance students' intuitive understanding, we use Korean for table and column names. Solving approximately 200 application problems on your own and working together to solve them will also be of great help.

Q. Who uses SQL and where?

It will primarily be used by IT developers. It's also essential for those who specialize in data analysis, visualization, and other data-intensive tasks. Anyone who handles any type of data in the workplace will find a solid understanding of SQL very helpful.

Q. What is the level of the class?

The entire course consists of eight sections, including both basic and advanced sections. Section 0 is the introductory course . As the course progresses, it gradually covers intermediate and advanced skills .

Q. Is it very different from ORACLE or MySQL?

Standard SQL is the same. Depending on the DBMS, some features, such as functions, may differ. Therefore, even if you learn with MS-SQL, Microsoft's DBMS with its excellent accessibility and online help, you'll have no trouble using SQL in ORACLE, MySQL, or other relational databases.
