Which term refers to data that provides information about other data?

1. Data integrity

2. Relational data

3. Metadata

4. Big data

The correct answer is: Metadata

The term that refers to data providing information about other data is metadata. Metadata serves as contextual information that helps to understand, manage, and organize data more effectively. For instance, metadata can describe the format, source, and creation process of a dataset, as well as information on its structure, such as columns and data types in a database. In contrast, the other terms do not encapsulate this definition. Data integrity focuses on the accuracy and consistency of data within a database, which does not specifically refer to data about other data. Relational data pertains to the organization of data in relation to other data sets, particularly in structured databases that utilize relationships among tables but does not indicate the characterization of the data itself. Big data describes data sets that are so large and complex that traditional data processing software cannot manage it, but it does not relate to the concept of describing that data. Thus, metadata is the correct answer as it directly embodies the concept of data that describes other data.
