First let me thank everyone who has answered questions here. I have used this site and others to gain a good understanding of database design. :)
Here is my question. When normalizing a database can you have multiple IDs in the same "link" table. Here is an example of what I mean.
Parts Table
PartNumberID
DescriptionID
Qty
RemarkID
SpecificationID
Of course each ID is a foreign key that links to a primary key on another table (i.e. PartnumberID links to the PartNumber table).
There have been many people in my department that feel when an ID is duplicated in this table it is no longer normalized. I looked online and generally they use very simple examples that would never answer this question.
Please all you DB experts any information would be helpful.
Thanks
