Online Shop Management System
A complete retail management solution with MVVM architecture and local data persistence
Project Overview
The Online Shop Management System is a comprehensive retail tool built using a strict MVVM 4-layer architecture (Presentation, Domain, Data, and Database layers) to ensure high maintainability and testability.
This application enables shop owners to manage products, track inventory, process sales, and generate reports — all with offline-first capabilities using local data persistence.

Use cases & business logic
Data Layer
Repositories & data sources
Database Layer
Room DB entities & DAOs
