Linking records to database based on ID

Question

Hi all,

 

I am working on a project using winforms in c#.

The problem is that, I want to have a PersonID.

I want to enter details (such as name, age profession et..) to the database, but I want those information to be linked to the PersonID in case I want to change any of the records that belogns to PersonID.

For example I want to save address that is linked to Person ID.

Then if I want to changed the address of that Person, I should be able to change the address by just typing PersonID of that person.

I need someone to tell me please how best I can do it. Shall I write classes? Please advise me on how best I have to do it. 

I hope I am clear.

Thanks in advance.

 

Regards
