This is a Windows Forms-based Accounting Software developed using a 5-layer architecture. The application communicates with a SQL Server database using the Database First approach, and follows Repository and Unit of Work design patterns for efficient data access and transaction management.

• User-friendly Windows Forms Interface: The application provides an intuitive interface for users to manage accounts, record transactions, and generate financial reports.
• 5-Layer Architecture: The project is structured to separate concerns across different layers:
  1. Presentation Layer (UI): Handles user interactions through Windows Forms.
  2. Application Layer: Contains business logic for accounting tasks.
  3. Domain Layer: Defines the core entities like Account, Transaction, etc.
  4. Data Access Layer: Manages data operations with Entity Framework (Database First).
  5. Infrastructure Layer: Provides support services like logging and configuration.

• Windows Forms: To build the desktop application interface.
• SQL Server: For storing all accounting-related data.
• Entity Framework (Database First): Models and database context are generated from the existing database schema.
• Repository Pattern: Abstracts database operations to promote flexibility.
• Unit of Work Pattern: Manages transactions across multiple repositories to ensure consistency.

1. Repository Pattern: Provides a clean abstraction layer over data access, ensuring that business logic is not tightly coupled to the database implementation.
2. Unit of Work Pattern: Ensures that multiple changes across different repositories are committed as a single transaction, providing consistency and integrity.

• Separation of Concerns: Each layer is dedicated to a specific responsibility, making the application easier to maintain and extend.
• Modular and Scalable: The architecture allows for easy updates or replacement of components without affecting the entire system.
• Consistency in Data Operations: Using Unit of Work ensures that all data changes happen within a single transaction, reducing the risk of data corruption.

1. Set Up the Database: Use SQL Server to create the database and then generate the models using the Entity Framework Database First approach. <<<<<<< HEAD
