@ctive data warehouse architecture has separate and segregated data marts
B
Correct answer
Explanation
The statement is False. Active data warehouse architecture (also called Active Warehouse Integration or Real-Time Warehouse) integrates and unifies data marts rather than keeping them separate and segregated. The active architecture approach creates a centralized, integrated environment where data marts share conformed dimensions and are coordinated, enabling real-time or near-real-time data integration across the enterprise.
