Which address field layout supports both structured queries and preserving original input?

• A. Store only a canonical address form
• B. Use a single unstructured field for all address data
• C. Use separate line1 and line2 fields plus a normalized address key and keep an unparsed street field
• D. Rely solely on a separate geographic coordinates field

Answer: (C)

Balancing structured querying with preserving original input. To search addresses effectively, you want separate fields for the components (line1 and line2, plus city, state, postal code) so you can run precise queries like “streets on Main” or “addresses in Seattle.” At the same time, keeping a normalized address key gives you a stable, standardized reference for matching and deduplication across varied formats. And preserving an unparsed street field ensures you keep the exact text as entered, including punctuation, abbreviations, and formatting, which is important for display, audit trails, and reformatting back to the user’s original input. This combination lets you perform structured queries while preserving the original input. Storing only a canonical form loses the exact user-entered text and limits precise component-based searches. Using a single unstructured field prevents meaningful queries by component. Relying solely on geographic coordinates removes the textual address components and the original input, making display and component-based searches impractical.
