Overview

Represents a data type definition from t_datatypes table

This table stores database-specific type definitions and mappings. It maps database vendor types (e.g., “VARCHAR2” in Oracle) to generic types (e.g., “varchar”). This is metadata for database schema generation, not UML DataType instances.

Examples:

datatype = EaDatatype.new
datatype.type #=> "DDL"
datatype.product_name #=> "Oracle"
datatype.data_type #=> "VARCHAR2"
datatype.generic_type #=> "varchar"
