Which of the following is NOT a characteristic of structured data?

Structured data is characterized by its highly organized format, which allows for easy analysis. It typically adheres to a predefined schema and consists of clearly defined fields that make it accessible and interpretable. Characteristics such as being stored in numeric or categorical formats further enhance its utility for analysis, as these forms can be easily aggregated and manipulated.

The notion that structured data is stored in files with limited organization contradicts its fundamental nature. Structured data is not defined by limited organization; rather, its very essence is a high level of organization, which is essential for effective data management and analytics. Therefore, identifying that characteristic aligns with the understanding of structured data as being well-organized and conducive to straightforward analysis.
