Data Element can point to _______ Domain?

  1. One

  2. Multiple

  3. Two

  4. None


Correct Option: A

AI Explanation

To answer this question, we need to understand the concept of data elements and domains.

A data element is a basic unit of data that represents a single attribute of an entity. It is used to define the structure and characteristics of data within a system or database.

A domain, on the other hand, is a set of allowable values for a data element. It defines the range or set of values that a data element can take.

Based on the given question, a data element can point to only one domain. This means that a data element can have a single set of allowable values, and it cannot have multiple sets of allowable values.

Let's go through each option to understand why it is correct or incorrect:

Option A) One - This option is correct because it states that a data element can point to one domain, which means it can have a single set of allowable values.

Option B) Multiple - This option is incorrect because it contradicts the correct answer. A data element cannot point to multiple domains.

Option C) Two - This option is incorrect for the same reason as option B. A data element cannot point to multiple domains.

Option D) None - This option is incorrect because it states that a data element cannot point to any domain. However, a data element must have a domain to define its set of allowable values.

Therefore, the correct answer is option A) One. This option is correct because a data element can point to only one domain, representing a single set of allowable values.
