Catalogue Architecture

NINA catalogue uses Django and PostgreSQL.

The software is made of different parts:

• Django, is the application server, it handles all the logic of answering to browser requests
• Queue, provides long running tasks, scheduled tasks and asyncronous executions
• PostgreSQL, is the database server, it stores the data
• NGINX, is the webserver, it shares user-uploaded files and static assets
• Varnish, provides a caching layer

Features inside the catalogue are organized as modules, each module aims to be as much independent as possible:

• Datasets
• Maps
