How to Configure Database in Django.

In Django database can be configured by setting the 'DATABASES' constant in settings.py file. For example:

If you want to configure and use SQLite as the default database then.

DATABASES = {
        'default': {
                        'ENGINE': 'django.db.backends.sqlite3',
			'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
		       }
	     }

or in order to define multiple databases in Django use the below configuration.

       DATABASES = {'default': {
				'ENGINE': 'django.db.backends.sqlite3',
				'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),   
				 },
				 'mysql': {
				          'ENGINE': 'django.db.backends.mysql',
					  'NAME': 'DbName',       
					  'USER': 'User',       
					  'PASSWORD': 'password',       
					  'HOST': 'db',          
					  'PORT': '3306',   
					 }
				   }
