All search engines use _____ data. Such data describes other data; logical…

Concept

Data categories are distinguished by what the records describe and why they are used. Metadata describes the meaning, structure, origin, or rules of another dataset; common examples include field names, data types, schemas, and logical database designs.

Operational data records current business events used in day-to-day transaction processing. Non-operational data is retained or prepared for analysis, reporting, and decision support, often as historical, aggregated, or externally sourced records.

Application

The stem points to information that describes another dataset and gives a logical database design as its example. Placing “Meta” in the blank forms “metadata,” the standard term for descriptive information about other data.

Contrast

• Operational data: live transaction records such as a newly placed order, a payment, or an inventory update.

• Non-operational data: historical or aggregated records used for trend analysis, reports, forecasting, or other decision-support work.

• Meta data: descriptions of another dataset, including schema names, field definitions, data types, constraints, and logical database designs.

• None of these: a set-level rejection of all named categories; it is not itself a data category or usage purpose.

Cross-check

In a database, an order row is operational data, a monthly sales summary is non-operational data, and the table definition that states each column name and data type is metadata. The example in the stem belongs to the metadata role.

Result

Therefore, the blank is filled by “Meta,” forming the term “metadata.”
