By the database site we refer to the URL where particular database can be managed. Each database has its own corresponding URL or site, eg: testdb1 has admin uri say – http://localhost:8000/testdb1_admin/ or testdb2 has admin uri say – http://localhost:8000/testdb2_admin/. If you are only interested in the source code, it is hosted in my github account here – To set up the project:-
