Hello guys, if you are a computer science graduate or new into the programming world and interested in learning Database and, SQL and looking for some awesome resources like books, courses, and tutorials to start with, then you have come to the right place.
If you don't know what SQL is and why you should learn it, let me give you a brief overview of SQL for everyone's benefit. SQL is a programming language to work with a database.
You can use SQL to create database objects like tables, stored procedure, etc and also to store and retrieve data from the database.
The SQL is one of the most important skills for any programmer, irrespective of technology, framework, and domain. It is even more popular than a mainstream programming language like Java and Python, and it definitely adds a lot of value to your CV.
SQL allows you to play with data, which is the most important asset of today's world. By learning SQL, you can get answers to your questions. For example, if you are a course creator for Udemy, a popular online course platform, and want to know which course is the best seller and which course is not selling at all, you can use SQL.
It can help in troubleshooting as well as reporting. Also, SQL is very stable technology and has been around for years, and it will be needed in the future. This means any investment you make in learning SQL will also serve you for a long time in your career.
