##Evidence:
Gold credit card owners refer to cards with type = 'gold' and disposition type = 'OWNER'. High balance accounts refer to accounts where avg_balance > 1000.

##Role Access Policy (Column-Level):
Role: DataOperator_2
Accessible Columns: account: account_id; card: card_id, disp_id, type; disp: account_id, client_id, disp_id; district: A10, A11, A12, A14, A15, A16, A2, A3, A4, A5, A6, A7, A8, district_id; loan: account_id, amount, duration, status; order: account_id, account_to, amount, k_symbol, order_id; trans: ALL COLUMNS
