To answer this question, you need to understand the concept of metadata. Metadata refers to data about data and provides information about the characteristics and properties of the data. Let's go through each option to understand why it is correct or incorrect:
Option A) Data about data - This option is correct because it accurately describes the concept of metadata.
Option B) Describe a data dictionary - This option is correct because a data dictionary is a type of metadata that provides descriptions and definitions of data elements.
Option C) Self-describing - This option is correct because metadata is designed to be self-describing, meaning it provides information about the structure, format, and organization of the data.
Option D) Includes user data - This option is incorrect because user data is not a characteristic of metadata. Metadata focuses on providing information about the data itself, rather than including user-specific data.
Option E) Supports its own structure - This option is correct because metadata often has its own structure and organization to ensure that it can effectively describe and represent the data it refers to.
The correct answer is Option D. This option is incorrect because including user data is not a characteristic of metadata. Metadata focuses on providing information about the data, rather than including specific user-related information.
