While it often seems obvious as to what the properties of each attribute are, you need to carefully consider what you expect to go into each field before deciding on it's properties. So consider carefully what data will be saved in the database and design accordingly. Also, make sure you future proof the database properties as much as possible.
Most often in a database this would be split into LastName and FirstName. Avoid using terms such as Christian Name, Surname, Family Name, as this does not work when dealing with many other cultures.
It is also common to add Preferred Name.
Fun Fact. How long?
The longest last name ever recorded was around 600 characters, but was mostly shortened to "Wolfeschlegelsteinhausenbergerdorff" (35 characters). (Wikipedia contributors, 2021)
A common way you will find addresses split is Street, Suburb, City, Post code, Country however this actually does not make sense in a lot of cases. For example;
Street - people also live in apartments or Flats and this can be the first line in their address (e.g. Flat 1B, etc)
Suburb, City - not everyone lives in a suburb or city
So as a suggestion use Address1, Address2, Town/City, PostCode, Country
It is tempting to put in a mask to make sure the users structure the phone number correctly. Unfortunately there are now such a range of formats that it is better to leave phone free format.
Some example phone numbers are +64 6 812-4567, 0800 123 4567, 877-1234, 027 1234 567
Interesting we use the term phone Number but the field is actually not a number . For a number you can think of something that counts or measures something e.g. Age, Quantity, however most phone numbers include things that are not a number e.g. spaces, brackets (), hashes, + signs etc.
If we are really accurate we probably should call the field "phone text" but I don't think that will ever catch on!
