in SAS data quality, a set of character values that have the same match code.

cross-reference table

a table that contains only the current rows of a larger dimension table. Columns generally include all business key columns and a digest column. The business key column is used to determine if source rows are new dimensions or updates to existing dimensions. The digest column is used to detect changes in source rows that might update an existing dimension. During updates of the fact table that is associated with the dimension table, the cross-reference table can provide generated keys that replace the business key in new fact table rows.

custom repository

in the SAS Open Metadata Architecture, a metadata repository that must be dependent on a foundation repository or custom repository, thus allowing access to metadata definitions in the repository or repositories on which it depends. A custom repository is used to specify resources that are unique to a particular data collection. For example, a custom repository could define sources and targets that are unique to a particular data warehouse. The custom repository would access user definitions, group definitions, and most server metadata from the foundation repository.
