Question
Data about data can best be defined as:a.End-user data DBMSb.Data dictionaryc.DBMSd.Meta data
Solution
The best definition for "data about data" is d. Meta data.
Here's why:
a. End-user data DBMS: This refers to the database management systems that are designed for end-users. It's not about data about data.
b. Data dictionary: This is a collection of descriptions of the data objects or items in a data model for the benefit of programmers and others who need to refer to them. While it does contain data about data, it's not the best answer because it's a specific tool, not the concept itself.
c. DBMS: This stands for Database Management System. It's a software for creating and managing databases. It's not about data about data.
d. Meta data: This is data that provides information about other data. In other words, it's "data about data". This is the best answer.
