Should I have area code stored in a separate field in my DB? It’s causing me a lot of pain in terms of parsing user input…but it would add value to have it searchable….but I’m not sure how much.
Right now we have the structure
We’re considering combining AreaCode and ExchangeAndSuffix.
What’s the standard practice here?
Thanks.
The question you have to answer is this: “Does a phone number represent a singular value, or does it represent several values who combine to form a singular tuple?” In other words, do you have actual logic (be it querying or business logic) that is dictated by these components (area code, exchange, etc.), or is a phone number just a phone number?
