Datengruppe

Datengruppe is a term used in data management and analytics to describe a logically defined collection of data elements or records that share common attributes or identifiers. A Datengruppe represents a subset of a larger dataset and is defined for purposes such as analysis, reporting, segmentation, or access control. Unlike a fixed database table, a Datengruppe can be a dynamic grouping produced by filters, labeling, or schema definitions, and it may be materialized as a view, a stored query, or a labeled collection in data platforms.

Formation and structure typically involve selecting records based on specified criteria, tagging data with group identifiers, or compiling related attributes into a cohesive unit. In practice, a Datengruppe can be stored as a view in a relational database, as a labeled collection in a data lake, or as part of a data warehouse schema. The composition of a Datengruppe is defined by its rules, which can be adjusted as data and requirements change.

Applications and use cases include customer segmentation by region or behavior, risk assessment by attribute combinations, and performance reporting for specific product categories. Datengruppe are also used to control access to sensitive data, enabling role-based permissions on particular subsets of information.

Data governance and privacy considerations apply to Datengruppe, including metadata management, lineage tracking, and adherence to data protection regulations. Anonymization or pseudonymization may be required for analytical groups involving personal data.
