databasebereik

Databasebereik is a term used in Dutch-language documentation and some technical writings to denote the scope or reach of data that a database or a component of a database can access or manage. The term combines database with bereik, meaning range or reach.

Definition and scope: Databasebereik can refer to several related ideas. It may describe the subset of records accessible from a given starting point via relations (reachability), the spatial or key range covered by an index or partition, or the data domain governed by a policy or access control within a system. In practice, the concept helps distinguish what data is available or handled by a subsystem at a given time.

Applications: In query planning, databasebereik helps determine which partitions or shards must be consulted. In data governance, it defines the data scope for a user role or service, ensuring access is limited to the allowed data. In data integration, it describes the intersection of datasets that can be joined or synchronized.

Measurement: The size or extent of the databasebereik can be expressed as cardinality (number of records), a key range width, or the time window of data covered, depending on the context (relational, spatial, or temporal).

Relation to other concepts: It relates to data scope, reachability, partition pruning, and access control. Unlike a fixed physical boundary, databasebereik can be dynamic as partitions migrate or policies change.

Notes: The term is not standardized in English-language literature and may appear primarily in Dutch or localized contexts. When communicating with a global audience, it is common to translate the concept as data scope or reachable data set.
