What is a data catalog primarily used for?
Answer: Providing a searchable inventory of an organization's data assets with metadata and lineage information

Answer: Tracing the origin, movement, and transformation of data throughout its lifecycle
Data lineage provides visibility into how data flows from source to destination and what transformations occur along the way, supporting debugging, compliance, and trust.
Which of the following is an example of structured data?
Answer: A relational database table with defined columns and rows
Structured data is organized into a predefined format with fixed fields, such as rows and columns in a relational database, making it directly queryable with SQL.
In the context of data management, what is 'schema-on-read'?
Answer: Applying the data structure interpretation when data is queried rather than when it is stored
