App Architecture Explained

Nearby Shops contain java based rest api in the backend which uses PostgreSQL as its primary database. It connects with PostgreSQL DB with type 4 JDBC driver. The database and api can be on one server OR we can also have a separate server for database. All the images and data are stored on the backend.

In the front end we have three android apps. End-User app, shop-owner app and admin app. These apps connect with the backend api using retrofit networking library.
