## 🏗️ Proposed Modular Structure

### Option 1: Category-Based (Recommended)

```

    └── cleanup.sh
```

### Option 2: Function-Based

```
scripts/
├── README.md
├── lib/                         # Shared libraries
├── deploy/                      # Deployment scripts

├── analyze/                     # Analysis scripts
└── setup/                       # Setup scripts
```

### Option 3: Hybrid (Recommended for Future)

```

```

## ✅ Recommended Approach: Option 1 (Category-Based)

### Benefits
1. **Clear Organization**: Easy to find scripts by purpose
2. **Scalable**: Can add subdirectories as needed
3. **Maintainable**: Related scripts grouped together
4. **Consistent**: Matches patterns from other projects

### Implementation Steps

1. **Create Directory Structure**
   ```bash
   mkdir -p scripts/{lib/{common,config},migration,metrics/{collect},dbis,infrastructure,utils}
   ```

2. **Create Shared Libraries**
   - Extract common functions to `lib/common/`
   - Create initialization script `lib/init.sh`

3. **Move Scripts to Categories**
   - Move scripts to appropriate directories
   - Update shebang paths if needed

4. **Create Wrapper Scripts** (Optional)
   - Create symlinks or wrapper scripts in root for backward compatibility

5. **Update Documentation**
   - Update README.md with new structure
   - Document library usage

## 📚 Shared Library Design

### Common Utilities (`lib/common/`)

#### `colors.sh`
```bash
# Color definitions for output
RED='\033[0;31m'
GREEN='\033[0;32m'
YELLOW='\033[1;33m'
NC='\033[0m' # No Color
```

#### `logging.sh`
```bash
# Logging functions
log_info() { echo -e "${GREEN}[INFO]${NC} $1"; }
log_error() { echo -e "${RED}[ERROR]${NC} $1"; }
log_warn() { echo -e "${YELLOW}[WARN]${NC} $1"; }
```

#### `utils.sh`
```bash
# Common utility functions
check_command() { command -v "$1" &> /dev/null; }
require_command() { check_command "$1" || { log_error "$1 not found"; exit 1; }; }
```

#### `validation.sh`
```bash
# Input validation functions
validate_project_name() { ... }
validate_environment() { ... }
```

#### `error-handling.sh`
```bash
# Error handling
set_error_handler() { ... }
cleanup_on_error() { ... }
```

### Configuration (`lib/config/`)

#### `env.sh`
```bash
# Environment loading
load_env() { ... }
require_env() { ... }
```

### Initialization (`lib/init.sh`)
```bash
# Initialize all libraries
source "$(dirname "$0")/common/colors.sh"
source "$(dirname "$0")/common/logging.sh"
# ... etc
```

## 🔄 Migration Strategy

### Phase 1: Create Structure (Non-Breaking)
1. Create new directory structure
2. Create shared libraries
3. Keep existing scripts in place

### Phase 2: Refactor Scripts (Gradual)
1. Update scripts to use shared libraries
2. Move scripts to new locations
3. Create wrapper scripts for backward compatibility

### Phase 3: Cleanup
1. Remove wrapper scripts after migration period
2. Update all documentation
3. Update CI/CD workflows
