Data Flow

  1. User Interaction: Users access web applications (Client/Admin/Technology) and mobile apps (iOS/Android)
  2. API Calls: Blazor components call Azure Functions via HTTP
  3. Service Layer: Functions invoke business logic services
  4. ML Processing: ML.NET services generate forecasts and predictions
  5. Data Access: Services use Entity Framework to query database
  6. File Operations: Generated reports stored in Azure Blob Storage
  7. Response: Data flows back through layers to user interface
