this might be a simple question, but I'll ask anyway :)
Lets say I got a table in a database (oracle) which is currently stored in the first normal form.
Now I would like to convert this table into the third normal form. But I don't exactly know how. OK, I know how to put the table into third NF on paper, no problem but how do I do it technically?
I'll just give an example:
My tabe has the following attributes: InvoiceNr. | Date | StaffNr. | Name | Lastname | Street | Zip | City
Now I would like to put it in the following format:
Table Invoice: InvoiceNr. (PK) | Date | StaffNr.
Table Staff: StaffNr. (PK) | Name | Lastname | Street | Zip
Table Zip: Zip (PK) | City
Thank you very much in advance ;) Thomas
