A team stores customer purchase records in a relational database with fixed columns and data types, then exports the table to train an ML model. According to AI data classifications, what type of data are these records?
Unstructured data
Semi-structured data
Time-series image data
Structured data
Relational tables contain highly organized information arranged in rows and columns with predefined data types. Such well-defined schema makes the content readily searchable and machine-readable, so it is classified as structured data. Unstructured data refers to free-form content like raw text, images, or audio that lacks a fixed schema. Semi-structured data (for example, JSON or XML) has some organizational tags but is not as rigid as a relational table. Time-series image data would be unstructured visual content collected over time, not a tabular dataset.
