Characteristics of data are contained within:
A. fields.
B. metadata.
C. columns.
D. records.
The correct answer and explanation is :
The correct answer is:
B. Metadata.
Explanation:
Data characteristics are contained within metadata, which is essentially “data about data.” Metadata provides critical information about the data, such as its structure, format, meaning, and how it should be used. It describes various aspects of data, including its type, constraints, relationships, and origin.
Understanding Metadata:
Metadata plays a crucial role in data management, ensuring that users can interpret and utilize data correctly. It typically includes:
- Descriptive metadata – Provides information about the content, such as titles, authors, and creation dates.
- Structural metadata – Defines how data is organized (e.g., tables, columns, relationships in a database).
- Administrative metadata – Includes technical details like file formats, access permissions, and data ownership.
Why Not the Other Options?
- A. Fields: Fields contain individual pieces of data within a record but do not describe the characteristics of the data itself.
- C. Columns: Columns store data attributes in a structured format but do not define the characteristics of the data.
- D. Records: Records are individual data entries that contain multiple fields but do not provide metadata.
Importance of Metadata:
Metadata is essential for data governance, organization, retrieval, and analysis. It helps databases, data warehouses, and analytical tools understand and interpret the stored data accurately.
