SQL short for Structured Query Language is a standard language for relational databases. Data is stored in relational databases and SQL is used for storing, manipulating and retrieving that data.
Thus, you will need to learn SQL for communicating with databases no matter which programming language you are using. Another important thing is that SQL can work with almost every kind of database to perform database operations.
Students find it very easy to learn language as it is just like you are writing English sentences. The advance concepts though require much logic and functions but you will learn the basics in no time.
