+# Database Implementation
+
+This document describes the PostgreSQL database implementation for the Software Release Management Platform.
+
+## Architecture Overview
+
+The database layer uses **Entity Framework Core 8** with **PostgreSQL 15** and includes:
+
+- **Soft Delete Pattern**: All entities support soft deletes with audit trail
+- **Repository Pattern**: Clean abstraction layer for data access
+- **Database Constraints**: Enforced data integrity at the database level
+- **JSON Support**: PostgreSQL JSONB columns for flexible configuration storage
+- **Migration Support**: Code-first database schema management
+- **Connection Pooling**: Optimized for high-performance applications
+

+
+## Soft Delete Implementation
+
+All entities inherit from `BaseEntity` with soft delete support:
+
+```csharp
+public abstract class BaseEntity
+{
+    public int Id { get; set; }
+    public DateTime CreatedAt { get; set; }
+    public DateTime UpdatedAt { get; set; }
+    public bool IsDeleted { get; set; }
+    public DateTime? DeletedAt { get; set; }
+    public string? DeletedBy { get; set; }
+    public string? CreatedBy { get; set; }
+    public string? UpdatedBy { get; set; }
+}
+```
+
+### Query Filters
+Entity Framework automatically filters out soft-deleted records:
+```csharp
+modelBuilder.Entity<User>().HasQueryFilter(e => !e.IsDeleted);
+```
+
+### Manual Override
+To include soft-deleted records:
+```csharp
+var allUsers = context.Users.IgnoreQueryFilters().Where(u => u.IsDeleted);
+```
+
+## Repository Pattern
+
+### Interface Example
+```csharp
+public interface IUserRepository
+{
+    Task<User?> GetByIdAsync(int id);
+    Task<User?> GetByUsernameAsync(string username);
+    Task<List<User>> GetAllAsync();
+    Task<User> CreateAsync(User user);
+    Task<User> UpdateAsync(User user);
+    Task DeleteAsync(int id, string deletedBy);
+    Task<bool> ExistsAsync(int id);
+}
+```
+
+### Benefits
+- Clean separation of concerns
+- Testable data access layer
+- Consistent error handling
+- Transaction management
+
+## Database Configuration
+
+### Connection String
+Production connection strings stored in `secrets.yaml`:
+```yaml
+Database:
+  ConnectionString: "Host=localhost;Port=5432;Database=software_release_management;Username=postgres;Password=your_secure_password"
+```
+
+### Performance Settings
+```json
+{
+  "Database": {
+    "CommandTimeout": 30,
+    "Pooling": {
+      "MinPoolSize": 5,
+      "MaxPoolSize": 100,
+      "ConnectionIdleLifetime": 300
+    },
+    "Retry": {
+      "EnableRetryOnFailure": true,
+      "MaxRetryCount": 5,
+      "MaxRetryDelay": 30
+    }
+  }
+}
+```
+
+## Setup Instructions
+
+### 1. Prerequisites
+- Docker and Docker Compose
+- .NET 8 SDK
+- PostgreSQL client tools (optional)
+
+### 2. Start Database
+```bash
+# Start PostgreSQL with Docker Compose
+docker compose up postgres -d
+
+# Optional: Start with PgAdmin
+docker compose --profile dev up -d
+```
+
+### 3. Run Migrations
+```bash
+cd src/Database
+dotnet ef migrations add InitialCreate
+dotnet ef database update
+```
+
+### 4. Seed Data
+```bash
+# Development environment automatically seeds test data
+ASPNETCORE_ENVIRONMENT=Development dotnet run
+```
+
+## Development Workflow
+
+### Creating Migrations
+```bash
+# Navigate to Database project
+cd src/Database
+
+# Create new migration
+dotnet ef migrations add MigrationName
+
+# Review generated migration files
+# Apply migration
+dotnet ef database update
+```
+
+### Database Scripts
+```bash
+# Generate SQL script for production deployment
+dotnet ef migrations script --output migrations.sql
+
+# Generate script for specific migration range
+dotnet ef migrations script PreviousMigration TargetMigration
+```
+
+### Data Seeding
+The database automatically seeds:
+- Default users (admin, user, readonly)
+- Storage providers (AWS S3, Box.com, FTP)
+- Help center providers (Zendesk, Salesforce)
+- Test projects and packages (development only)
+
+## Security Features
+
+### Password Hashing
+- BCrypt with work factor 12
+- Automatic salt generation
+- Secure password verification
+
+### Secrets Management
+- Production secrets in `secrets.yaml`
+- Environment variable overrides
+- Docker secrets support
+
+### Database Security
+- Connection pooling limits
+- SQL injection protection (parameterized queries)
+- Role-based access control
+- Audit logging
+
+## Performance Considerations
+
+### Indexing Strategy
+- Primary keys (clustered indexes)
+- Foreign key relationships
+- Query optimization indexes:
+  - `Users.Username` (unique)
+  - `Projects.CCNetProjectName` (unique)
+  - `Builds.StartTime`, `Builds.Status`
+  - `FogBugzCases.LastUpdated`
+  - `Publications.Status`, `Publications.PublishedAt`
+
+### JSON Column Usage
+PostgreSQL JSONB columns provide:
+- Efficient storage and querying
+- Flexible configuration schemas
+- GIN index support for complex queries
+
+### Connection Pooling
+- Configured connection limits
+- Idle connection cleanup
+- Health check monitoring
+
+## Monitoring and Maintenance
+
+### Health Checks
+```csharp
+services.AddHealthChecks()
+    .AddDbContextCheck<DatabaseContext>("database");
+```
+
+### Logging
+- Entity Framework query logging
+- Migration execution logs
+- Performance monitoring
+- Error tracking
+
+### Backup Strategy
+```bash
+# Database backup
+pg_dump -h localhost -p 5432 -U postgres -d software_release_management > backup.sql
+
+# Restore from backup
+psql -h localhost -p 5432 -U postgres -d software_release_management < backup.sql
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Connection Issues**
+   ```bash
+   # Check PostgreSQL status
+   docker compose logs postgres
+   
+   # Test connection
+   psql -h localhost -p 5432 -U postgres -d software_release_management
+   ```
+
+2. **Migration Failures**
+   ```bash
+   # Reset migrations (development only)
+   dotnet ef database drop --force
+   dotnet ef database update
+   ```
+
+3. **Performance Issues**
+   ```sql
+   -- Check slow queries
+   SELECT query, mean_time, calls 
+   FROM pg_stat_statements 
+   ORDER BY mean_time DESC LIMIT 10;
+   ```
+
+### Support
+- Check Entity Framework documentation
+- Review PostgreSQL logs
+- Monitor application performance
+- Use PgAdmin for database administration
+
+## Next Steps
+- Set up monitoring and alerting
+- Implement database backup automation
+- Configure read replicas for scaling
+- Set up connection string encryption
