A data dictionary is being developed for a dataset describing a company's customer base. Within the data dictionary, which of the following represents a composite data element?

AStreet address

BFirst name

CTotal sale

DBirthdate

Show Suggested Answer

Suggested Answer: A

A composite data element is a data element that is made up of smaller units called sub-elements, which are separated by a sub-element separator character, such as a colon (:). For example, ITEMNO is a composite data element that consists of three sub-elements: part number, aisle number, and bin number. A street address is also a composite data element that can consist of sub-elements such as street number, street name, city, state, and zip code. First name, total sale, and birthdate are simple data elements that do not have sub-elements.

Hmm, this is a tough one. I'm going to go with the answer that has the most syllables - C. Total sale. It just sounds more complex, you know?

I'm going with B. First name. It's a single, non-composite data element.

C. Total sale is a good candidate for a composite data element, as it could be derived from other data points like individual purchase amounts.

That makes sense, Birthdate does have multiple components like day, month, and year.

I disagree, I believe it's Birthdate because it consists of multiple parts.

D. Birthdate seems like the obvious choice here. It's a single, atomic data element.

I think the answer is A. Street address is a composite data element, made up of multiple components like street name, house number, etc.

No, Total sale is not a composite data element. It is a single data element representing the total amount of sales.

I'm not sure, but I think it could be Total sale. It might be made up of different components.
