Add the legacy database model

I added the legacy database model into the app.

In order to do that I:

- created the urls.py and views.py file (required by Django)
- created the legacy model using the inspectdb tools given by Django and
stored in models.py
- followed the process to initialize the migrations at the stage of the
model (resulting in the creation of the migrations folder)
