▶ About this video:
There is no doubt that databases are a crucial element of any IT system. You may also know there are two main types of databases: relational and non-relational. But could you tell the core difference between them? Let’s take a closer look.

What’s a relational database?
A relational database is a database that forms relations between tables that store data on specific entities. A relational database uses SQL, Structured Query Language.

What’s a non-relational database?
NoSQL databases are more flexible because the data on the object isn’t limited to the same table. Non-relational databases use columns and rows to enter types of data and its values and identify objects with keys.
