Introduction to database

00:05.000 --> 00:10.000
In this video, we will understand what a database is and its key features.

00:10.000 --> 00:13.000
Explain why databases are important in digital systems.

00:13.000 --> 00:18.000
Identify types of databases, relational and non-relational.

00:18.000 --> 00:24.000
Learn when to use relational and non-relational databases.

00:25.000 --> 00:33.000
Behind every app, website or online system, there's one powerful technology keeping everything organized.

00:33.000 --> 00:35.000
The database.

00:35.000 --> 00:41.000
It's the digital brain that stores, connects and powers the world's information.

00:41.000 --> 00:45.000
The database is the crucial link for all digital services.

00:45.000 --> 00:53.000
It's the central engine that allows code and processes to manage data, ensuring the entire system runs consistently and reliably.

00:54.000 --> 00:58.000
A database is a structured collection of data for this system flow.

00:58.000 --> 01:02.000
Designed for efficient storage, retrieval and management.

01:02.000 --> 01:10.000
Unlike simple blocks, databases keep information consistent, secure and fast to access throughout.

01:10.000 --> 01:17.000
Databases power almost every digital service you use, from online shopping to social media.

01:17.000 --> 01:21.000
They help store and manage millions of records at lightning speed.

01:21.000 --> 01:26.000
There are two types of databases, relational and non-relational.

01:26.000 --> 01:30.000
Relational databases use tables with structured relationships,

01:30.000 --> 01:37.000
while non-relational databases are flexible and can store data in formats like graphs.

01:37.000 --> 01:47.000
Today, databases are mostly cloud-based, capable of handling large-scale data for analytics, using Amazon and Google Cloud services.
