KomplexFeldtyp
KomplexFeldtyp (German for "complex field type") is a data-type concept used in data modeling, databases, and form design to represent values that consist of multiple subfields and may be nested or repeated. It contrasts with primitive field types such as string, integer, or boolean by providing a structured container for related data. A KomplexFeldtyp defines a collection of subfields, each with its own type, constraints, and optionality. Subfields can be primitive or other complex types, allowing arbitrary nesting and, in many systems, support for arrays and maps.
In practice, a KomplexFeldtyp supports validation at the subfield level and may impose cross-field rules. Serialization
Common use cases include form data capture with structured responses, API payload schemas, content metadata, configuration
As a simple example, a KomplexFeldtyp called "Address" might contain subfields: street (string), city (string), and
