SQL is specially designed for accessing and manipulating databases. Over the course of the past few years, SQL has garnered immense popularity in multiple domains, including database administration, backend web development, Data Science, and Business Intelligence (BI). These fields involve storing and retrieving colossal volumes of data for data analysis, which makes SQL skills a must.  

Data Science uses tools to derive, mine, and analyze data to solve business problems. SQL is a querying language tool that works on manipulating and handling relational databases to manage and analyze the data in specific methods- seeking to extract fruitful results.

It is an efficient management system aimed at simplifying the tedious process of extracting data from the mountainous pile of databases by plating the role of a language communicator between the human operating the collection and the computer system carrying the load. The commands are the language inputs that the other end of the software understands.
