Application architecture

How the components work together

  1. Interface Responsive browser UI Presents cashier, payment, receipt, dashboard, and reporting workflows.
  2. Web application ASP.NET Core MVC Coordinates routes, validation, workflow state, and user-facing responses.
  3. Business logic Calculation service Calculates Item Discount, synthetic SST, payment allocation, quick Cash, and change.
  4. Data access EF Core data access Maps seven focused tables and keeps sale confirmation consistent.
  5. Database SQL Server 2022 Stores the synthetic catalogue, confirmed sales, payments, and receipt records.
Local verification Isolated SQL Server container

Local development can run SQL Server 2022 in a dedicated Podman container bound to the computer's loopback address. This keeps CloudPosDemo records isolated from other databases. A hosted environment supplies its SQL connection through environment configuration; credentials are not stored in source.

Demonstration boundary

This application uses synthetic products and Customers. Cash, Card, and E-Wallet are simulated labels that do not contact payment providers or move funds. Synthetic SST demonstrates configurable calculation behavior only; it is not an SST return or compliance service. The demo does not post accounting journals, manage stock, process refunds, or use real Customer data.
