-# Excel Pajak Application
-
-## Project Overview
-
-Excel Pajak is a .NET 10.0 console application that connects to a PostgreSQL database to handle tax-related data processing. The application is designed to execute database queries and process employee information, with a focus on connecting to specific database schemas containing employee data.
-
-### Architecture
-- **Main Application**: Console application in the `excel_pajak` directory
-- **Test Project**: Unit and integration tests in the `excel_pajak_test` directory
-- **Technology Stack**: 
-  - .NET 10.0
-  - PostgreSQL database connectivity via Npgsql
-  - Microsoft.Extensions.Configuration for configuration management
-  - MSTest for unit testing
-  - Moq for mocking dependencies
-  - Shouldly for assertions
-
-### Key Components
-
-1. **DatabaseService** (`Services/DatabaseService.cs`): Handles PostgreSQL connections and executes scalar queries
-2. **EmployeeInfo Model** (`Models/EmployeeInfo.cs`): Represents employee data structure with employee number and schema
-3. **Configuration**: Managed through `appsettings.json` with connection strings and application settings
-4. **Examples**: Demonstrates JSON deserialization of employee data
-
-## Building and Running
-
-### Prerequisites
-- .NET 10.0 SDK
-- PostgreSQL database server (version compatible with Npgsql 10.0.1)
-- Access to the configured database (default connection points to localhost:55432)
-
-### Build Commands
-```bash
-# Restore dependencies
-dotnet restore
-
-# Build the application
-dotnet build
-
-# Run the application
-dotnet run --project excel_pajak/excel_pajak.csproj
-
-# Run tests
-dotnet test
-```
-
-### Configuration
-The application uses `appsettings.json` for configuration:
-- Connection string for PostgreSQL database
-- Schema list (currently contains "_onx4pzkwkeortehfjthgyfkb7c")
-- Year setting (currently "2025")
-
-## Development Conventions
-
-### Coding Standards
-- Uses nullable reference types (`#nullable enable`)
-- Follows .NET naming conventions
-- Implements asynchronous programming patterns where appropriate
-- Includes proper error handling with specific exception types
-
-### Testing Approach
-- Unit tests for business logic with mocked dependencies
-- Integration tests that connect to actual PostgreSQL database
-- Tests cover both positive and negative scenarios
-- Uses Shouldly for readable assertions
-
-### Error Handling
-- Validates input parameters and throws appropriate exceptions
-- Handles database connection errors gracefully
-- Provides detailed error messages for debugging

-
-## Database Connection
-The application connects to PostgreSQL using Npgsql with the connection string defined in `appsettings.json`. The default configuration connects to:
-- Server: localhost
-- Port: 55432
-- Database: andal_kharisma
-- User: postgres
-- Password: Release@2024
-
-## Testing
-The project includes both unit tests (with mocked dependencies) and integration tests (requiring a live database connection). Unit tests validate the logic without external dependencies, while integration tests verify actual database connectivity and query execution.
-
-To run integration tests, ensure that a PostgreSQL database is accessible with the configured connection string.
