Have a PC with internet connection
If you have watched both part 1 and part 2 of my database courses, you will nail the concepts of this course. Else if you are comfortable with basics like key, primary key, basics of relational algebra – going through this course willnot be a problem


You’ve just stumbled upon the most in-depth SQL course online. With over 6000 students enrolled and 900+ 5 star reviews to date in the area of computer science, my computer science courses are enjoyed by students from 114 countries. Whether you want to:- build the skills in database management- build the skills in sql- crack interview questions on sql of database management system.- or just understand data is fetched from database using sql….this complete Masterclass on SQL is the course you need to do all of this, and more.Are you aiming to get a degree in the area of computer science as a topper ? This course is designed to give you the skills you need to answer any question on SQL . By the end of the course you will understand SQL topics of Database Management extremely well and be able to answer any question on these topics for interview.Lots of students have been successful with getting their first job or a promotion after going through my courses on computer science.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.
