Domain-Driven Design (DDD) Structure

The system follows a clean architecture approach, organizing components into core domains and layers to ensure maintainability, scalability, and adherence to business logic.

Domains

1. Booking Domain

   • Entities:
     • Booking: Represents a reservation, including customer details, event details, and schedule.
     • Customer: Stores information about the individual or group making the booking.
   • Value Objects:
     • TimeSlot: Specifies the start and end time of a booking.
     • BookingStatus: Enum to define states (e.g., Pending, Confirmed, Cancelled).

2. Inventory Domain

   • Entities:
     • InventoryItem: Represents a stock item, such as a drink or supply.
     • Supplier: Represents suppliers providing stock items.
   • Value Objects:
     • StockLevel: Encapsulates current stock levels and reorder thresholds.
     • ItemCategory: Enum for categorizing inventory (e.g., Beverages, Miscellaneous).

3. External Providers Domain

   • Entities:
     • Provider: Represents external food providers or restaurants.
     • FoodOrder: Tracks orders placed with providers, linked to bookings.
   • Value Objects:
     • MenuItem: Represents an item offered by an external provider, including pricing.
     • OrderStatus: Enum to define the state of an order (e.g., Pending, Delivered).

4. Accounting Domain

   • Entities:
     • Transaction: Represents financial transactions (income or expense).
     • Expense: Tracks operational costs, such as salaries or maintenance.
   • Value Objects:
     • TransactionType: Enum to classify transactions (e.g., Revenue, Expense).
     • PaymentMethod: Enum for payment modes (e.g., Cash, Mobile Money).

5. Payment Domain

Key Layers

1. Core

   • Contains the domain models, entities, value objects, and interfaces.
   • This layer encapsulates the business logic and rules.

2. Application Layer

   • Contains use cases (application services) that orchestrate operations involving domain objects.
   • Example Use Cases:
     • MakeBooking
     • TrackInventory
     • GenerateInvoice

3. Infrastructure Layer

   • Implements external integrations like database access, payment gateways, and API calls.
   • Example Components:
     • Repository patterns for entities (e.g., BookingRepository).
     • Mobile money API adapters.

4. Presentation Layer

   • The user interface for interacting with the system.
   • Provides options for web or mobile implementations (e.g., React, Angular, or Flutter).
