ModellDatenSchema

ModellDatenSchema is a formal description of the data structures that underlie a software model. It specifies the objects or entities, their attributes, the relationships between them, the allowed data types, and the constraints that govern valid data. The schema acts as a contract that enables consistent data storage, transmission, and validation across components and systems involved in the model-driven lifecycle.

Typical elements include entities or classes, property definitions, keys (primary and foreign), cardinalities of relationships, and constraints such as required fields, default values, and uniqueness. Metadata such as version, namespace, authorship, and provenance may be included to support evolution and governance. Schemas may also model inheritance, composition, and polymorphic relationships as appropriate to the modelling approach.

Formats and technologies used to express ModellDatenSchema vary. Common representations include JSON Schema, XML Schema, or language-specific modeling definitions embedded in development environments. Tools can validate data against the schema, generate code, create database schemas, or produce documentation and test data from the schema.

Applications include model-driven engineering, data integration, API design, and system interoperability. By providing a common data contract, ModellDatenSchema helps ensure data quality, simplifies migration and synchronization, and supports automated testing and deployment pipelines.

While the exact form of ModellDatenSchema depends on the modelling approach, it typically emphasizes clarity, extensibility, and backward compatibility, enabling evolution of the model without breaking existing consumers.
