Yes, it is possible to link Django with multiple databases simultaneously.

Django provides support for multiple databases in its ORM (Object Relational Mapping) layer. You can define multiple database connections in your Django project's settings.py file, and then specify which database to use in your models or views using the using() method.

Here's an example of how to create multiple database connections in your Django project's settings.py file:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'mydatabase',
        'USER': 'mydatabaseuser',
        'PASSWORD': 'mypassword',
        'HOST': 'localhost',
        'PORT': '',
    },
    'second_db': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'myseconddatabase',
        'USER': 'myseconddatabaseuser',
        'PASSWORD': 'mypassword',
        'HOST': 'localhost',
        'PORT': '',
    }
}

You can then specify which database to use in your models or views using the using() method. For example:

class MyModel(models.Model):
    my_field = models.CharField(max_length=100)

    class Meta:
        # specify which database to use for this model
        using = 'second_db'

You can also specify which database to use in your views using the using argument when querying the database. For example:

from myapp.models import MyModel

# query using the default database
default_db_objects = MyModel.objects.all()

# query using the second database
second_db_objects = MyModel.objects.using('second_db').all()

Note: If you are using multiple databases, you will need to specify which database to use when creating migrations for your models. You can do so using the --database option when running the makemigrations command. For example:

python manage.py makemigrations --database=second_db
