Database Operations

SQL and Relational Databases

Relational databases are the primary means of storage for structured data. They organize data into tables that each contain data related to one another.

We commonly use SQL, which stands for Structured Query Language, to query and play around with relational databases. This programming language is designed to manage data stored in relational databases.

We can visualize a relational database in the image of tables below.

This image shows a relational database. The lines in the diagram show that certain rows within each table are interconnected, showing off the idea of a relational database.
