Which statement about data warehouses is true in healthcare organizations?

• A. They are small, department-specific data stores only
• B. They are large collections of data from multiple sources used to support decision making
• C. They are used exclusively for billing
• D. They contain only unstructured data

Answer: (B)

Data warehouses in healthcare are enterprise-scale repositories that integrate data from multiple sources to support decision making. They collect data from electronic health records, billing systems, laboratories, imaging, pharmacy, and administrative systems into a centralized store, preserving historical information to enable trend analysis, quality reporting, and population-health insights. This makes them large collections of data from diverse sources that support informed decisions across the organization. They are not just small department-specific stores, nor are they used solely for billing, and they do not contain only unstructured data—these warehouses are built around structured data to allow efficient querying and analytics, with unstructured data sometimes brought in via complementary tools.
