## Overview
**Relational database management systems (RDBMS)** offer an intuitive **user interface**, making them accessible even to those with limited experience. They organize data into tables that interrelate.

**Non-relational database management systems**, on the other hand, provide a specialized interface tailored primarily for developers. They store data in distinctive formats, not in tables. Of these formats, **JSON (JavaScript Object Notation)** stands out as the most prevalent.

For illustration, consider two datasets named "**student**" with the fields: **id**, **name**, **surname**, and **age**. Below is how these datasets might be represented in both relational and non-relational database contexts:

**Data in non-relational databases** often resemble **dictionary-like structures**, akin to those in Python. Below is an example showcasing this relationship:

Here, we have student data associated with the group **BG1**. Unlike relational systems, there's no direct linkage present. The non-relational system (or NoSQL DBMS) is responsible for identifying this association.

We'll dive deeper into the intricacies of relational databases as we progress in this course.
