Hi,

I'd like to know if a composite attribute (e.g., a subject code like 'CS2323', where 'CS' denotes the department and so on) can be in a relation or whether this is prohibited by the definition of relation. In other words, does the definition of relation prohibit composite attributes or only multivalued attributes?.

I've got the same doubt regarding the first normal form. Depending on the text, I get a different opinion about the answer to this question.

Thanks in advance Received on Mon Nov 18 2002 - 16:26:03 CST
