Stage 3: Document data rules as SBVR fact types and rule statements
Knobit of Data modelling · K-305 · Skill
Recognises overlapping value-set rules on one fact type
What it means
Two value-set rules on one fact type. The permitted set becomes their intersection, which is never what either author meant.
How it is assessed
Flags the deficient case and passes the acceptable one. Deficient: `BR-6: account status is one of OPN, DOR, CLS`; `BR-8: account status is one of OPN, DOR, CLS, BLK` Acceptable: One value set, versioned, owned by a steward; if the narrower set is a project-phase decision, say so in the rule (`ANO-005`)
