Where are the names, addresses, and phone numbers typically stored?

• A. In a notebook
• B. In a breadbox
• C. In a calendar
• D. In a database

Answer: (D)

Storing names, addresses, and phone numbers as structured data in a database makes sense because a database is designed to hold many records with defined fields (name, address, phone) and keep them consistent. It lets you search, sort, update, and report quickly, and it scales as your contacts grow. You can also relate different pieces of data (like emails or company names) without duplication. A notebook is manual and easy to lose or misread, a breadbox isn’t a data storage system, and a calendar is meant for dates and events, not comprehensive contact records. So a database is the most efficient and reliable choice for this kind of information.
