A relational database is a set of tables from which data can be accessed in many different ways without reorganizing the database tables.
The data is accessed through queries, and there's a language to do just that called Structured Query Language (SQL).
We live in the information age. Information is derived from data
This is an example I took from my professor.
Data: 500
Information: 500 miles
Knowledge: 500 miles is a far distance.
Wisdom: 500 miles is far to walk. I'd better drive.
Data from: Introduction to database
We use the data everyday like to go find streaming platform, gaming, soical media, and even from the cloud storage of our phones.
