Why would you choose to learn SQL ?

The reality is that there is a lot of SQL courses out there. It's in the hundreds. Why would you choose my courses ?

The number one reason is its simplicity. According to many students in udemy, my courses are simple to understand as I always teach concepts from scratch in a simple language.

The second reason is you get a mentor for computer science through this course. I get lot of doubts from students regarding their career in computer science like which elective subject to choose, which book to refer, etc.

The third reason is, you are not just watching my videos, you can also ask doubts if you get one while watching the lectures.

Which text book should you refer ?

I have used Database System Concepts by Korth. Its a great textbook. You can follow it. But I have referred lot of other textbooks like Navathe, Sudharshan etc. So its upto you on which textbook you are comfortable with but follow a standard author book. If you complete this course, you will find it much easier to understand these textbooks. But anyway if you complete this course with good detailed notes, you don't need to read any textbook as I am reading them for you and giving the contents in an easy to understand manner.

Why should you take this course?

You will be joining over 6000 students who are already enrolled in my courses.

There are 1500+ reviews left by students. My Courses are rated as the best course to learn computer science for beginners.

What makes this course a standout?

Like you, thousands of others were frustrated and fed up with incomplete Youtube tutorials which assume you already know a bunch of stuff and also bulk textbooks able to send even the most intuitive person to sleep.

Like you, they were tired of low-quality lessons, poorly explained topics and all-round confusing info presented in the wrong way. That’s why so many find success in my courses. It’s designed in a simple manner so that anybody will be able to understand.

What if I have questions?

You can ask questions anytime using the Q/A section or through personal messages. I take it very seriously and answer these questions in a detailed manner with simple english words so that anybody can understand it.
