SQL is the most common language for extracting and managing data stored in relational databases.
A database is a table of rows and columns. SQL is the language of the database. It facilitates the retrieval of specific information from the database which is then used for analysis.
Even when analyzing on another platform like Python or R, SQL will be required to extract the required data from the company’s database.
There are different versions and frameworks for SQL, the most widely used is MySQL. MySQL is an open source solution that helps simplify the role of SQL in back-end data management for web applications.
Companies like Facebook, Instagram, WhatsApp etc. They use SQL for back-end data storage and processing solutions. When a SQL query is written and executed (or parsed), it is processed by the Query Optimizer.
What is SQL used for?
Now that we understand what SQL is and how it works, let’s try to see what SQL can do. This programming language has various uses for data analysts and data science professionals. This is especially useful because it can:
