Fachdatenmodell

A Fachdatenmodell, often translated as a domain data model or subject data model, is a conceptual representation of the data specific to a particular business domain or subject area. It focuses on defining the entities, their attributes, and the relationships between them as they exist within that specific field, rather than a general-purpose or technical data structure. The primary goal of a Fachdatenmodell is to capture the essential business logic and rules governing the data, ensuring it accurately reflects the real-world concepts and operations of the domain.

These models are crucial for understanding, communicating, and managing information within an organization or a specific industry. They serve as a common language for stakeholders, including business analysts, domain experts, and IT professionals, facilitating clear communication and reducing ambiguity. By abstracting away technical implementation details, a Fachdatenmodell provides a high-level view that can be easily understood by non-technical users.

The development of a Fachdatenmodell typically involves identifying key concepts (entities), their characteristics (attributes), and how these concepts relate to each other (relationships). This process often involves extensive collaboration with domain experts to ensure completeness and accuracy. The resulting model can then inform the design of databases, applications, and data integration strategies, ensuring that IT systems are aligned with business needs and effectively support the operations of the specific domain.
