1️⃣ What is a Database?
A database is an organised collection of data stored in a computer system (typically a server machine, but can be any machine) so that it can be accessed and managed easily.
✪ Initially each database had a separate way of data management. The way one database was storing and managing data may vary from another.
✪ But with time this practice got normalised. The "Relational Database" design came into picture.
