-## Database
-Following SQL script is used to create a MySQL database for storing users and videos data.
-```sql
-#create database
-CREATE DATABASE live-stremaing;
-
-#switch to newly created database
-USE live-streaming;
-
-#create users table
-CREATE TABLE `users` (
-  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
-  `username` varchar(45) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
-  `password` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
-  `created` datetime DEFAULT NULL,
-  `modified` datetime DEFAULT NULL,
-  PRIMARY KEY (`id`),
-  UNIQUE KEY `username` (`username`)
