"Databases are representations of reality"
The national ID example is funny. Let me give you a dose of reality concerning national IDs.
- I've seen cases with my country's national ID numbers containing duplicates due to human error.
- National ID's for people can change. In my country, children being adopted, get a different ID after adoption.
- There exist people without a national ID. Or people that don't want you to know their national ID.
- HelloNurse 1y agoDon't forget general patterns, e.g. you positively need to enter a record right now, but they didn't tell you what "key" to use; or they misspelled the "key" and you have to update it by user request.
