Commercial databases used in cancer registries include which of the following?

• A. Microsoft PowerPoint
• B. Microsoft SQL
• C. Microsoft Word
• D. Microsoft Excel

Answer: (B)

Managing cancer registry data requires a robust system that can store large, related datasets, enforce data integrity, and support secure, multi-user access. A commercial database management system like Microsoft SQL provides a relational environment ideal for this work. It lets you organize information into related tables (for example, patients, tumors, treatments, and follow-up), enforce primary and foreign key relationships to keep data consistent, and use ACID transactions to ensure accuracy even when many users are entering data at once. It also offers indexing and querying capabilities, scalable storage, security controls, and reporting options that registries need to produce reliable statistics and comply with standards. In contrast, the other options are not database systems. Word is for document creation, PowerPoint for presentations, and Excel is a spreadsheet tool. Excel can hold data but lacks robust relational modeling, strong multi-user support, and comprehensive data integrity controls necessary for a cancer registry’s complex, interrelated data.
