This course was created for those who find databases challenging, making it easy to understand concepts and build your skills through practice. This lecture covers database fundamentals and SQL language usage. For learning how to create databases, you can take the database design course. Since most program developers encounter databases in their work, I've made an effort to explain in detail how to approach databases from a programmer's perspective.

This course does not teach the grammar of C#. It simply uses C# as a tool for designing object-oriented programs. This course covers in depth the essential content that intermediate and higher level programmers need to know, as well as the content that is essential to developing programs that are linked to databases.

This is the second lecture following the Database Design Fundamentals course. This is a practical course that focuses on real-world projects from start to finish. After understanding all the lecture content, you will be able to freely design databases.

This course is mainly about ADO.NET and will be practiced with WinForms programs using the C# language. In addition, it will explain various fields such as database design, SQL writing, stored procedure writing, and libraries and transactions created with ADO.NET through practical programming through sample projects.

This course is not focused on C# grammar. It focuses on understanding and creating classes. It covers basic grammar, but it also includes a lot of practical program writing tips because it goes through many examples.

This course is an easy-to-understand explanation of database design theory, focusing on practical exercises. Most people who have experienced it through books, etc. have probably felt that database theory was difficult and given up. I did the same. However, if you know it, you will find that it is an easy and very interesting field. In this course, the design content is organized so that you can understand it just by looking at it.

This course is for those who are learning database programming for the first time or those who have some knowledge but want to learn systematically. From concepts to practical exercises, you will master the database query language by organizing examples of types that frequently occur in real life.

This course is for those who are learning programming for the first time. The lectures are not boring at all. Most of the lectures proceed through examples after a simple explanation.
