**Validation Methods:**
- Null value analysis
- Record count validation
- Gap detection
- Source system verification

**Metrics:**
- Completeness percentage
- Missing value rates
- Gap frequencies
- Source availability

### Dimension 2: Accuracy
**Definition**: Validates data correctness and format compliance.

**Key Aspects:**
- **Value Accuracy**: Data values are correct
- **Format Accuracy**: Data follows expected formats
- **Type Accuracy**: Data types are appropriate
- **Business Rule Accuracy**: Business logic correctly applied

**Validation Methods:**
- Range checking
- Format validation
- Type verification
- Business rule testing
- Manual sampling

**Metrics:**
- Error rates
- Format compliance rates
- Type validation success
- Business rule pass rates

### Dimension 3: Consistency
**Definition**: Ensures data alignment across systems and over time.

**Key Aspects:**
- **Cross-System Consistency**: Data alignment between systems
- **Temporal Consistency**: Data stability over time
- **Referential Consistency**: Relationship integrity
- **Standard Consistency**: Adherence to standards

**Validation Methods:**
