Cardinality in Framework Manager defines the numerical relationship between two tables (1:1, 1:N, N:1, or N:N) regardless of table type. It can represent relationships between fact and dimension tables (common in star schemas), between dimension tables (when dimensions relate to each other), or between any other tables in the model. Cardinality affects how Framework Manager generates SQL and handles joins. Option D is incorrect because cardinality is defined per relationship, not by data source.
