Section 22: Onwards To Databases: Beyond Simple File Storage

The goals

💪🏻What & Why?

✌🏻SQL vs NoSQL Databases

 

Why do we need a database?

Up to this point, we typically stored our (simple) data in files.

SQL database has tables and it's structurized. We can find the specific data we want with a head row.

 

We have standalone documents that contain all the data that belongs to a single document.

In this case, if we can fetch more data with fewer queries.

And we don't have to clearly set schema.

 

SQL vs NoSQL - Which one should we choose?
