A contact center for a service company is capturing audio calls to understand user sentiment. These digital files lack defined fields and metadata. Which best describes this category for the original audio recordings?
They are unstructured data without row-and-column organization
They are partially structured data with standardized delimiters
They are stored in a table-based model with consistent fields
They are intangible numeric data that fit binary fields
These audio files do not have a prescribed schema, so they do not align with rows and columns. They are unstructured data. Labeling these files as table-based would require a predefined structure. Calling them partially structured would imply a consistent delimiter, which does not exist in raw audio. Treating them as numeric data in fields is incorrect because audio typically requires waveform or binary representation rather than numeric columns.
