What is Structured Query Language (SQL) primarily used for?

Evaluating business metrics
Communicating with a database
Analyzing complex data sets
Defining the scope of work

The correct answer is: Communicating with a database

Structured Query Language (SQL) is primarily used for communicating with a database. It provides a standardized way to perform various operations on data stored in a relational database, including retrieving, inserting, updating, and deleting data. SQL allows users to interact with the database in a precise and efficient manner by formulating queries that specify what data is needed and how it should be returned. While evaluating business metrics, analyzing complex data sets, and defining the scope of work are important tasks in data analytics, they are not the primary function of SQL. Rather, these tasks often utilize the results obtained from SQL queries to drive insights and decision-making. SQL’s core purpose revolves around managing and manipulating database information, making it an essential tool for data analysts and anyone who works with databases.
