+## Traditional Data Type Mapping
+## Advanced DuckDB Type System
+
+The driver provides the most comprehensive DuckDB type system integration available, achieving **100% DuckDB utilization** through three implementation phases:
+
+### Phase 2: Advanced Analytics Types (80% Utilization)
+
+**Complex Data Structures:**
+
+- **StructType** - Nested data with named fields for hierarchical storage
+- **MapType** - Key-value pair storage with JSON serialization
+- **ListType** - Dynamic arrays with mixed types and nested capabilities
+
+**High-Precision Computing:**
+
+- **DecimalType** - Configurable precision/scale for financial calculations
+- **IntervalType** - Years/months/days/hours/minutes/seconds with microsecond precision
+- **UUIDType** - Universally unique identifiers with optimized storage
+- **JSONType** - Flexible document storage for schema-less data
+
+### Phase 3: Ultimate DuckDB Features (100% Utilization)
+
+**Core Advanced Types:**
+
+- **ENUMType** - Enumeration values with validation and constraint checking
+- **UNIONType** - Variant data type support with JSON serialization  
+- **TimestampTZType** - Timezone-aware timestamps with conversion utilities
+- **HugeIntType** - 128-bit integer arithmetic using big.Int integration
+- **BitStringType** - Efficient boolean arrays with binary operations
+- **BLOBType** - Binary Large Objects for complete binary data storage
+- **GEOMETRYType** - Spatial geometry data with Well-Known Text (WKT) support
+
+**Advanced Operations:**
+
+- **NestedArrayType** - Multi-dimensional arrays with slicing operations
+- **QueryHintType** - Performance optimization directives with SQL generation
+- **ConstraintType** - Advanced data validation rules and enforcement
+- **AnalyticalFunctionType** - Statistical analysis functions with window operations
+- **PerformanceMetricsType** - Query profiling and monitoring with detailed metrics
+
